'''Hypermedia''' formats combine text, graphics, audio, video, and executable code, with the ability to link them to one another.

'''Hypertext''' is a subset of hypermedia, in which the document consists entirely or primarily of text.

* [[ufsdump]]
* [[Unix dump]]
* [[Windows Imaging Format]] (.wim, .swm)

== Self-extracting archives ==
(in addition, some of the other archivers are able to produce executable files for some platform which include the archived data and a program to extract them, and generally have the file extension normal for executables, such as .exe for DOS/Windows. In many cases, if you rename the extension to the appropriate one for the archive type involved, e.g., '''.zip''', the file will open in the appropriate archiver, which is handy for extracting them on systems not compatible with the original executable.)

'''Gwtar''' (pronounced like "guitar") is a format for storing a full webpage in a single HTML file, developed in 2026 by Gwern Branwen and Said Achmiz.

The format was developed as a convenient solution for archiving webpages, which would satisfy three criteria:
* the full contents of the webpage, including images, scripts, etc. must be stored locally;
* the webpage and all its assets must be stored as a single file;
* users can browse the archived webpage without having to first download the entire file (parts of the file with webpage assets are downloaded as needed).

A Gwtar file consists of three parts:
* the header - a combination of [[HTML]], [[JavaScript]], and [[JSON]], which contains the actual HTML markup, as well as scripts which handle piece-by-piece download of the rest of the file;
* all of the webpage resources, stored in [[Tape Archive|tarball]] format;
* any other arbitary data (e.g. metadata, [[Security#Electronic signatures|electronic signature]]s, [[Error detection and correction|error correction]] codes).

Mah Jongg -V-G-A- tile set

Havoc Crow: /* Further reading */ added MobyGames external link

{{FormatInfo
|formattype=electronic
|subcat=Graphics
|extensions={{ext|tis}}, {{ext|til}}, {{ext|icn}}, {{ext|cfg}}
|released=≤1989 (TIL/ICN), 1989 (TIS)
}}
This article describes the tile set graphics formats associated with '''Mah Jongg VGA''' (stylized as '''Mah Jongg -V-G-A-''', and sometimes abbreviated '''MJVGA'''), a ''Mahjong solitaire'' game for DOS by Ron Balewski. (Note that there are several different accepted spellings of ''Mahjong''.)

A tile set may consist of a single '''.TIS''' file (supported by v2.1+), or it may be broken down into 44 '''.TIL''' files (named V00.TIL to V43.TIL) and one PAL.CFG file.

Early versions of the game use extension '''.ICN''' for the TIL files. It is the same format.

TIS format is also supported by '''Mah Jongg for Windows''' (sometimes abbreviated '''MJ/Windows''' or '''MJWIN'''), by the same author.

Compare to [[Mah Jongg (Nels Anderson) tile set]].

== Identification ==
TIL files seem to always start with the same 6 bytes: {{magic|a6 05 2b 00 3b 00}}. They are exactly 1448 bytes in size.

A TIS file consists of a 96-byte header, followed by a sequence of 44 embedded TIL files, followed by a variable-sized palette. So, bytes {{magic|a6 05 2b 00 3b 00}} appears at offset 96. Given the structure of the palette, the total file size should be from 63920 to 63968 bytes.

== Software ==
Utilities often included with the software:
* The Draftsman, a tile set editor
* VIEWSET.EXE, a pattern set viewer
* UNPAKTIL.COM/PAKTIL.COM, utilities to convert from TIS to TIL and vice versa

Attorney Online

2025-10-18T11:25:59Z

Havoc Crow: /* Log and demo format */ small clarification

{{FormatInfo
|formattype=electronic
|subcat=E-Mail, newsgroups, and forums
|extensions={{ext|log}}, {{ext|demo}}
}}

'''Attorney Online''' (also known as '''AO''' or '''Ace Attorney Online''') is an open-source chatroom program, designed for online roleplays in a [[wikipedia:visual novel|visual novel]]-like format inspired by the ''[[Wikipedia:Ace Attorney|Ace Attorney]]'' game franchise. In visual novel style, each participant takes on a specific character and can select predefined poses to accompany their dialogue, displayed over a static background.

== Network packet format ==
AO operates on a client–server model, with a single server exchanging network packets with connected clients (players’ computers). Each packet corresponds to an in-game event, such as a music change, an in-character (IC) line of dialogue, or an out-of-character (OOC) system message.

The network packets are documented here:
* https://github.com/AttorneyOnline/docs/blob/master/docs/Archive/Network%20Protocol.md

== Log and demo format ==

By default, during a play session Attorney Online records both bare-bones textual log files and complete demo files. These files are created in the /logs/ subfolder, with the extensions <code>.log</code> and <code>.demo</code> respectively.

A log is a plain-text dump of all the IC and OOC messages seen by the client, with timestamps.

Example excerpt from a .log file:
<pre>
[Sat Aug 2 05:35:35 2025 GMT] Gumshoe: Howdy all
[Sat Aug 2 05:35:45 2025 GMT] Gumshoe: Here are three dollar signs: $$$
[Sat Aug 2 05:36:22 2025 GMT] Gumshoe: I am angry now.
[Sat Aug 2 05:36:36 2025 GMT] Gumshoe: This is my angry face.
[Sat Aug 2 05:36:53 2025 GMT] Gumshoe has played a song: Ace Attorney/Trial/[AJ] Trial.opus
</pre>

A .demo file is a plain-text dump of all the network packets received by the client, interspersed with "wait" commands to record the time (in miliseconds) between each packet. Therefore, a demo file records the session (as seen from a single player's point of view) to its smallest detail. Demos can be played back in the client to obtain a near-perfect recreation of the RP session.

Example excerpt from a .demo file (same session as the .log file excerpted above):
<pre>
MS#1#-#Gumshoe#normal#Howdy all#wit#1#0#8#1#0#0#0#0#0#Gumshoe#-1###0<and>0#0#0#0#0#0#-^(b)normal^(a)normal^#-^(b)normal^(a)normal^#-^(b)normal^(a)normal^#0#||#-1###0#0##%

MC#Ace Attorney/Trial/[AJ] Trial.opus#8##1#0#2#%

In pre-2.9.1 versions of the official Attorney Online client, the demo files are generated incorrectly: the "wait" packet is incorrectly placed ''after'' the message it's meant to delay. This was [https://github.com/AttorneyOnline/AO2-Client/pull/496 fixed in v2.9.1]. Newer Attorney Online versions detect these malformed demo files and offer to fix them before playback.

Jigwin piece template

2025-09-19T00:46:30Z

Havoc Crow: /* The format */ clarify max vertex limit

{{FormatInfo
|formattype=electronic

}}

The '''Jigwin piece template''' is a file format used by the [[Jigsaws Galore]] program. It defines the shape of a "fun piece": a fancifully-shaped puzzle piece which can appear in jigsaw puzzles alongside normal-shaped pieces.

The "fun piece" feature was added in version 6 (2005), which comes with 22 pre-made Jigwin piece templates and explains the format in its help file. To be recognized by the program, a template file must have the <code>asc</code> extension and be placed in the Pieces/ subfolder.

The pre-made files all start with the line <code>Jigwin piece template version 1.0</code>, hence the title of this article. The name "Jigwin" refers to the Jigsaws Galore executable, <code>jigwin.exe</code>.

== The format ==

Jigwin piece template files are plaintext lists of vertex coordinates.

An example Jigwin piece template (<code>square.asc</code>, one of the default ones bundled with version 6) looks as follows:
<pre>
Jigwin piece template version 1.0
Title: Square
Author: David P. Gray
Corners: 1,2,3,4
1, 0.0, 0.0
2, 1.0, 0.0
3, 1.0, 1.0
4, 0.0, 1.0
</pre>
The format is pretty self-explanatory. Some notes: (Checked as of Jigsaws Galore version 6)
* The initial metadata section must contain a line starting with <code>Corners:</code>. This line specifies the ids of the four vertices which are the corners of the piece, in the order: top-left, top-right, bottom-right, bottom-left.
* The <code>Title:</code> and <code>Author:</code> lines are optional. They specify the title and author name that will be displayed by Jigsaws Galore in the fun piece settings dialog.
* Any other lines in the metadata section are ignored.
* After the initial metadata, each row contains a vertex id number (integer), and x, y coordinates (floats or integers). Coordinates can be positive or negative, and given to any scale or precision; the program automatically resizes the piece to match the other jigsaw pieces. There can be of course more than four vertices listed (it's unknown if there's any specific limit to their number).
* The vertices must be listed in increasing order, starting from 1, without repetitions or gaps in id numbers. This section of the file cannot contain any lines other than vertex definitions. The final line can end with a newline character, but this is not required.
* The piece templates bundled with the program sometimes have additional numbers after the coordinates, e.g. <code>1,0.330000,9.210000,0.000000,1</code>. However, the help file clarifies that those extra numbers are ignored. (Perhaps they're the leftovers of some cut feature.)

'''Jigsaws Galore''' is a shareware jigsaw puzzle program, originally developed by David P. Gray for Windows in 1996. As of 2025, it is still actively maintained and sold, with the latest release being version 7, available for both Windows and macOS. The program allows users to both solve existing puzzles and create new ones from their own images.

Jigsaw Galore is associated with the following file formats:

* '''Jigsaw puzzle files''', with the extension .jsm. Each file contains a single jigsaw puzzle, including image data, default piece number and shapes, and metadata such as the puzzle's title and author. The program comes bundled with several pre-made .jsm puzzles.
** Somewhere around version 7 the format was entirely changed. It is known that version 6.02 cannot read .jsm files from version 7.14, and vice versa. In particular, metadata is no longer kept in the .jsm file, but rather in an external .ini file in the program's jigsaw folder.
* '''Savegame files''', with the extension .jss, which preserve the progress of solving a particular puzzle.
** As of version 7.14, it is not possible to make savegames manually. Instead the game maintains autosaves for each puzzle.
* '''[[Jigwin piece template|Piece templates]]''' (.asc). Plaintext files which define fancy piece shapes (pig, fish, square etc.). Each such file is a list of vertex coordinates. See article for details.

Doom DWD

Havoc Crow: add clarification about modern map editors

{{FormatInfo
|formattype=electronic
|subcat = Game data files
|extensions = {{ext|dwd}}
|released = 1993
}}
'''DWD''' is a game map format used by DoomEd, the in-house level editor used by id Software to create the levels for the game Doom. Maps in DWD format were used as input to the map compiler DoomBSP, which converted them to the [[Doom WAD]] format.

Unlike the WAD format, which is binary, DWD files are plaintext files, which list all lines and objects on the map in fairly human-readable format.

Third-party Doom map editors do not use the DWD format, instead saving the created maps directly in WAD format.

Attorney Online

Havoc Crow: /* Log and demo format */ copyediting

{{FormatInfo

|subcat=E-Mail, newsgroups, and forums
|extensions={{ext|log}}, {{ext|demo}}
}}

'''Attorney Online''' (also known as '''AO''' or '''Ace Attorney Online''') is an open-source chatroom program, designed for online roleplays in a [[wikipedia:visual novel|visual novel]]-like format inspired by the ''[[Wikipedia:Ace Attorney|Ace Attorney]]'' game franchise. In visual novel style, each participant takes on a specific character and can select predefined poses to accompany their dialogue, displayed over a static background.

== Network packet format ==
AO operates on a client–server model, with a single server exchanging network packets with connected clients (players’ computers). Each packet corresponds to an in-game event, such as a music change, an in-character (IC) line of dialogue, or an out-of-character (OOC) system message.

The network packets are documented here:
* https://github.com/AttorneyOnline/docs/blob/master/docs/Archive/Network%20Protocol.md

== Log and demo format ==

By default, during a play session Attorney Online records both bare-bones textual log files and complete demo files. These files are created in the /logs/ subfolder, with the extensions <code>.log</code> and <code>.demo</code> respectively.

A log is a plain-text dump of all the IC and OOC messages seen by the client, with timestamps.

Example excerpt from a .log file:
<pre>
[Sat Aug 2 05:35:35 2025 GMT] Gumshoe: Howdy all
[Sat Aug 2 05:35:45 2025 GMT] Gumshoe: Here are three dollar signs: $$$
[Sat Aug 2 05:36:22 2025 GMT] Gumshoe: I am angry now.
[Sat Aug 2 05:36:36 2025 GMT] Gumshoe: This is my angry face.
[Sat Aug 2 05:36:53 2025 GMT] Gumshoe has played a song: Ace Attorney/Trial/[AJ] Trial.opus
</pre>

A .demo file is a plain-text dump of all the network packets received by the client, interspersed with "wait" commands to record the time (in miliseconds) between each packet. Therefore, a demo file records the session to its smallest detail. Demos can be played back in the client to obtain a near-perfect recreation of the RP session.

In pre-2.9.1 versions of the official Attorney Online client, the demo files are generated incorrectly: the "wait" packet is incorrectly placed ''after'' the message it's meant to delay. This was [https://github.com/AttorneyOnline/AO2-Client/pull/496 fixed in v2.9.1]. Newer Attorney Online versions detect these malformed demo files and offer to fix them before playback.

A '''polyglot''' is a [[source code]] or [[file]] which constitutes valid data in two or more distinct formats simultaneously.

An example of a '''polyglot file''' would be an image file which can be viewed normally, but also contains embedded [[ZIP]] data, which can be read by changing the file extension to .zip and opening it in a decompression program.

A '''polyglot program''' is source code which can be interpreted in two or more different programming languages.

'''tweetable-polyglot-png''' by David Buchanan is an open source Python script to pack up to 3MB of data into a tweetable [[PNG]] [[polyglot]] file.

Hosts where this works:
* Twitter/X
* Imgur
* Github repo thumbnail/header image
* Discord

Hosts where it doesn't work:
* Reddit (Perhaps it could be made to work by embedding data within the DEFLATE stream, rather than appending?)

Twitter strips unnecessary data from PNG uploads, however, they do not strip trailing data from the DEFLATE stream inside the IDAT chunk, provided that the overall image file meets the requirements to avoid being re-encoded.

The cover image must compress well, such that the compressed filesize is less than (width * height) - size_of_embedded_file. If the cover image does not have a palette, then it must have at least 257 unique colors (otherwise Twitter will optimize it to use a palette).

The resolution can be up to 4096x4096, however, be aware that Twitter will serve a downscaled version by default, for images greater than 680x680 (depending on your display DPI, etc.).

The image should not have any unnecessary metadata chunks.

The total output file size must be less than 3MB (maybe 5MB?), otherwise Twitter will convert the PNG to a JPEG.

If the embedded file is a .zip, then the offsets are automatically adjusted so that the overall file is still a valid zip. For any other file formats, you're on your own (many will work without any special handling, notably .pdf, .mp3).

'''Puffchat''' is a [[Snapchat]] competitor, claiming to offer secure chatting with messages that self-destruct after they are read. Unfortunately, somebody figured out that its API wasn't really very secure, and its messages didn't really self-destruct. The founder of the service reacted by going berzerk and making legal threats against anybody who mentioned these flaws on the Web or Twitter, demanding that all such mentions be taken down immediately. Of course, this led to the information being disseminated much more widely, per the [[Wikipedia:Streisand effect|Streisand Effect]].

{{FormatInfo

|subcat=E-Mail, newsgroups, and forums
|extensions={{ext|log}}, {{ext|demo}}
}}

'''Attorney Online''' (also known as '''AO''' or '''Ace Attorney Online''') is an open-source chatroom program, designed for online roleplays in a [[wikipedia:visual novel|visual novel]]-like format inspired by the ''[[Wikipedia:Ace Attorney|Ace Attorney]]'' game franchise. In visual novel style, each participant takes on a specific character and can select predefined poses to accompany their dialogue, displayed over a static background.

== Network packet format ==
AO operates on a client–server model, with a single server exchanging network packets with connected clients (players’ computers). Each packet corresponds to an in-game event, such as a music change, an in-character (IC) line of dialogue, or an out-of-character (OOC) system message.

The network packets are documented here:
* https://github.com/AttorneyOnline/docs/blob/master/docs/Archive/Network%20Protocol.md

== Log and demo format ==

By default, during a play session Attorney Online records both bare-bones textual log files and complete demo files. These files are created in the /logs/ subfolder, with the extensions <code>.log</code> and <code>.demo</code> respectively.

The logs are a plain-text dump of all the IC and OOC messages seen by the client, with timestamps.

Example excerpt from a .log file:
<pre>
[Sat Aug 2 05:35:35 2025 GMT] Gumshoe: Howdy all
[Sat Aug 2 05:35:45 2025 GMT] Gumshoe: Here are three dollar signs: $$$
[Sat Aug 2 05:36:22 2025 GMT] Gumshoe: I am angry now.
[Sat Aug 2 05:36:36 2025 GMT] Gumshoe: This is my angry face.
[Sat Aug 2 05:36:53 2025 GMT] Gumshoe has played a song: Ace Attorney/Trial/[AJ] Trial.opus
</pre>

A .demo file is simply a plain-text dump of all the network packets received by the client, interspersed with "wait" commands to record the time (in miliseconds) between each packet. Therefore, a demo file records the session to its smallest detail. Demos can be played back in the client to obtain a near-perfect recreation of the RP session.

DeHackEd patch

'''DeHackEd''' is an unofficial editor created by Greg Lewis for the computer game Doom. It allows users to modify the game's behavior by directly editing the executable file. DeHackEd can modify the behavior of the in-game objects, change their properties and flags, edit text strings, and adjust a few other values.

Modifications implemented with DeHackEd can be distributed as plaintext "patch files", by default with the extension .deh. A DeHackEd patch file lists all the changes to the game logic in the form of human-readable key=value pairs.

Many Doom mods use .deh files to modify the game beyond what is possible with custom [[Doom WAD]] files. Originally, players had to run DeHackEd manually to apply the patch to their Doom executable. Modern Doom source ports can interpret DeHackEd patches directly via a command line option, without modifying the executable. Additionally, many ports can handle DeHackEd patches embedded directly within WAD files.

== Sample files ==

Numerous DeHackEd patches can be found in the [https://www.doomworld.com/idgames/ /idgames] Doom mod archive. This includes:
* standalone DeHackEd patches, for example:
** "[https://www.doomworld.com/idgames/utils/exe_edit/patches/kaboom Land-mines for DEATHMATCH]"
** "[https://www.doomworld.com/idgames/utils/exe_edit/patches/flame12 Flamethr.deh]"
* Doom total conversions with included .deh patches, for example:
** "[https://www.doomworld.com/idgames/themes/batman/batman Batman DOOM]"
** "[https://www.doomworld.com/idgames/levels/doom2/a-c/allhell All Hell is Breaking Loose!!!]"

'''DWD''' is a game map format used by DoomEd, the in-house level editor used by id Software to create the levels for the game Doom. Maps in DWD format were used as input to the map compiler DoomBSP, which converted them to the [[Doom WAD]] format.

Unlike the WAD format, which is binary, DWD files are plaintext files, which list all lines and objects on the map in fairly human-readable format.

==Overview==
Many popular games use proprietary file formats to store their assets. These include custom image, sound and video formats and custom archive formats. There is no way that all of these can be enumerated here in some way or another. And as long as the games can still be run by an [[Emulation_Software|Emulator]] it's not that much of a deal. However, a lot of work has been put into deciphering, decrypting and hacking these files, and that work should be preserved.

See also: [[Interactive Fiction]] for data formats related to text adventure games, [[Puzzles]] for puzzle-game files, and [[Saved Games]] for data saved by games to store a player's game status.

'''DataSAFE''' is a Windows archival and encryption program created by Authentex Corporation. It creates encrypted, password-protected file archives in two formats: safe files (.saf) and lockbox files (.lbx). According to the help file of v1.15 (1996), the files use [[LZ77]] compression and [[Blowfish]] encryption.

The program actually includes two separate executables: "Authentex DataSAFE" (SAFE32.exe - for creating and opening .saf files) and "Authentex Lockbox" (LOCKBX32.exe - for creating and opening .lbx files). Both programs are big on skeuomorphism: creating a new .saf or .lbx file involves 'opening' a virtual box, putting in the files, 'closing' the box, then 'locking' it via a combination, all accompanied by appropriate visuals. The passwords must be 8 characters long (numbers, letters, or symbols).

== .saf files versus .lbx files ==

Both .saf and .lbx files are essentially the same thing - password-protected archives. Per the developer's intention, the lockbox files (.lbx) are meant to be nested within .saf files, thus creating sub-archives with their own individual passwords.

It's not clear if there's any internal difference between the two file formats. Based on testing of DataSAFE v1.15 under Windows 98, the most apparent difference is that SAFE32.exe allows more features: it allows to create self-extracting executable archives, or to attach a plaintext note metadata to the .saf file. LOCKBX32.exe lacks these features.

In fact, .saf files and .lbx files can be freely nested within each other, in any combination and to any depth. However, nesting .lbx files within the .saf file is more convenient, as it's possible to run any number of instances of LOCKBX32.exe alongside a single copy of SAFE32.exe; thus, upon 'opening' the safe, each lockbox within can be immediately opened separately. On the other hand, you cannot run more than one instance of SAFE32.exe at a time; therefore nesting .saf files within each other is a bit inconvenient, since you need to close and reopen the program to open the deeper safes.

== Identification ==

.saf files created by v1.15 start with the string <code>2DataSAFE File, Copyright 1996, Authentex Software</code>

.lbx files created by v1.15 start with the string <code>8Lockbox Program File, Copyright 1996, Authentex Software</code>

(often a filesystem-level capability, such as ZFS and Btrfs snapshots and Windows Shadow Copy)

* [[Autodesk Vault]]
* [[SmartVersion]] (.svf)

See also [[Development#Revision_control_systems_.2F_code_repositories|Revision control systems / code repositories]]

== Encrypted or cryptographically signed archives ==
* [[DataSAFE]] (.saf, .lbx)
* [[SDN (SDN Project)]]
* [[XIP]]
* [[ZED]]

== File splitting ==
(1 file => multiple files. Most file splitting utilities just produce raw file fragments, and don't have a native file format. But some use a container format, and some create a separate "control" file for metadata.)

* [[AS/ZC (Zip Chunker)]]
* [[AUTOCHOP]]
* [[LambChop]]
* [[SLICE (Ziff Communications)]]
* [[SPLIT (M. Dingacci)]]

Also, the two sorts of [[Horcrux]], [[Horcrux (jesseduffield)]] and [[Horcrux (kndyry)]], are split-and-encrypted files.

== Filesystem backup and restoration ==
Formats designed for backing up disks, usually specifically targeted at particular [[filesystem]]s (but backing it up in the form of file structures, not raw sector images like [[Disk Image Formats]]).
* [[BACKUP (MS-DOS)]]
* [[Partimage]]
* [[ufsdump]]
* [[Unix dump]]
* [[Windows Imaging Format]] (.wim, .swm)

See also [[Backup]].

== Fake archiving ==
Beware of these; they purport to be archivers but aren't really; you might lose any data you entrust to them. Could be somebody's idea of humor or malware.
* [[OWS (fake compressed archive)]]
* [[WIC (fake compressed archive)]]

== Institutional archiving ==
* [[ARK]] (identifier for archived documents)
* [[Archive eXchange Format]] (.axf)
* [[OAIS]] (Open Archival Information System, an organization that does archiving)
* [[Planets Core Registry]]
* [[PRONOM]]
** [[PUID]]
* [[SIRF]] (Self-Contained Information Retention Format)
* [[Submission Information Package]]
* [[UPF]] (Universal Preservation Format)

== Metadata formats ==
* [[Archive Team hostname file]]
* [[CDX]] (associated with web archives)
* [[DFDL]] (Data Format Description Language) - a file format for describing file formats
* [[FilmConservationMetadata]]
* [[Internet Archive metadata]]
* [[mtree]]
* [[Portland Common Data Model]]
* [[TOSEC Naming Convention]]
* [[Web Archive Metadata File]] (metadata for [[WARC]])

== Self-extracting archives ==
(in addition, some of the other archivers are able to produce executable files for some platform which include the archived data and a program to extract them, and generally have the file extension normal for executables, such as .exe for DOS/Windows. In many cases, if you rename the extension to the appropriate one for the archive type involved, e.g., '''.zip''', the file will open in the appropriate archiver, which is handy for extracting them on systems not compatible with the original executable.)

== Self-extracting archives ==
(in addition, some of the other archivers are able to produce executable files for some platform which include the archived data and a program to extract them, and generally have the file extension normal for executables, such as .exe for DOS/Windows. In many cases, if you rename the extension to the appropriate one for the archive type involved, e.g., '''.zip''', the file will open in the appropriate archiver, which is handy for extracting them on systems not compatible with the original executable.)

'''FloorPlan''' is a series of floor plan CAD software, created by the company IMSI. Its versions are variously named '''FloorPlan Plus''', '''FloorPlan Plus 3D''', or '''FloorPlan 3D'''.

The initial version of the software represents everything as a collection of 2D shapes. Starting with v3 (?), the structures can also be associated with 3D models. Later versions represent all structures as 3D models.

== Associated formats ==

=== Floor plan design files ===

The actual floor plans created by the program. Known versions of this format:

* "Floorplan/DOS drawings" (.fpd) - so called in FloorPlan Plus 2.0's import dialog.
* "Floorplan/Windows drawings" (.fpw) - so called in FloorPlan Plus 2.0's import dialog.
* FloorPlan Plus 2.0 for Windows (.fp2)
** Identification: Files start with the string <code>FloorPlan Plus/3D Drawing File</code>
* FloorPlan Plus 3D, v3.01 (.fp3)
** Identification: Files start with the string <code>FloorPlan Plus/3D Drawing File</code>
* FloorPlan 3D building (.bmf) - saved by FloorPlan 3D.
** Identification: Files created by v7.3.330 of the program start with the bytes <code>08 00 00 00 2c 00 00 00</code>, followed by the string <code>FloorPlan3D (cr: "7.3.330"; mod: "7.3.330")</code>.

=== Symbol libraries ===

Early FloorPlan versions allow to save a set of 2D shapes as a "symbol" which can then be reused repeatedly (e.g. to represent various types of furniture). Starting with FloorPlan 3.0, it's possible to additionally associate a 3D model with a symbol. Symbols are organized into symbol library files.

FloorPlan Plus 2.0 and 3.0 for Windows uses the .lib extension for symbol libraries. It can also import "Floorplan/DOS libraries" (.lib) and "Floorplan/Windows libraries" (.wol).

==== Identification ====

A .lib file created by FloorPlan Plus 2.0 or 3.0 begins with the string <code>FPWIN/3D Symbol Library Version 1.0</code>. The name of the library is stored in plaintext, starting at offset 0x2C.

=== Styles ===

Style files (.sty) are collections of predefined styles for architectural elements, such as floors, walls, or wiring.

==== Identification ====

A .sty file created by FloorPlan Plus 2.0 or 3.0 begins with the string <code>FloorPlan Plus/3D Stock Styles</code>.

Windows System Information file

Havoc Crow: +cat (XML based file formats)

{{FormatInfo
|formattype=electronic
|subcat=System files
|extensions={{ext|nfo}}
}}
The System Information application in Windows (also known as <code>msinfo32.exe</code>) displays detailed technical information about the system. It allows users to export this data to a '''System Information file''', which by default uses the <code>.nfo</code> extension. System Information files can be reopened in the same application for later viewing. These files can be used for technical diagnostics and troubleshooting.

== Format ==

An .nfo file is encoded in [[plain text]] and structured using [[XML]] syntax. There doesn't seem to be an official specification, but it has a very simple structure. The data is organized into nested categories and subcategories (same as those displayed in the System Information app), each containing one or more entries represented as rows of data with named columns. These column names correspond to the headers displayed in the System Information app.

Here's an example file structure, using placeholder values:
<pre>
<?xml version="1.0"?>
<MsInfo>
<Metadata>
<Version>8.0</Version>
<CreationUTC>07/30/25 12:10:25</CreationUTC>
</Metadata>
<Category name="Category Name 1">
<Data>
<Column_Name_1><![CDATA[Value for item 1's column 1]]></Column_Name_1>
<Column_Name_2><![CDATA[Value for item 1's column 2]]></Column_Name_2>
</Data>
<Data>
<Column_Name_1><![CDATA[Value for item 2's column 1]]></Column_Name_1>
<Column_Name_2><![CDATA[Value for item 2's column 2]]></Column_Name_2>
</Data>
</Category>
<Category name="Category Name 2">
<Category name="Subcategory Name 1">
<Data>
<Another_Column_Name_1><![CDATA[Value for item 1's column 1]]></Another_Column_Name_1>
<Another_Column_Name_2><![CDATA[Value for item 1's column 2]]></Another_Column_Name_2>
<Another_Column_Name_3><![CDATA[Value for item 1's column 3]]></Another_Column_Name_3>
</Data>
<Data>
<Another_Column_Name_1><![CDATA[Value for item 2's column 1]]></Another_Column_Name_1>
<Another_Column_Name_2><![CDATA[Value for item 2's column 2]]></Another_Column_Name_2>
<Another_Column_Name_3><![CDATA[Value for item 2's column 3]]></Another_Column_Name_3>
</Data>
</Category>
</Category>
</MsInfo>
</pre>

The category names and column names vary depending on the system language. The file is generated without no indentation, and [https://superuser.com/questions/1855000/is-msinfo32-able-to-read-nfo-files-containing-indentation adding indentation seems to cause slight glitches in file parsing.]

The above file structure is the same for Windows 7 Pro and Windows 10 Pro versions of <code>msinfo32.exe</code>. The value in the <code><Version></code> tag is 8.0 in both cases.

Havoc Crow: info on .kce files

{{FormatInfo
|formattype=electronic
|subcat=Database
|extensions={{ext|kcd}}, {{ext|kce}}
}}
'''KCD''' is a file database format used by the Polish program '''KatalogCD'''. The program is designed to catalogue the contents of CDs and other media, such as hard drives. For a given medium, KatalogCD can automatically create a contents database. By default, only the folder structure is recorded; file information is stored only if explicitly requested, by providing a filename pattern for acceptable files.

A single KatalogCD database file can store information for multiple discs. For each disc, the folder and file structure is stored. Each disc, folder, and file entry can be associated with text metadata.

== Identification ==

KCD files appear to always begin with the byte sequence <code>4A 53 5A 46 80</code>. The first four bytes correspond to the ASCII string <code>JSZF</code>. The letters "JSZ" may be a reference to the program's developer, Jacek Szpyrka (who is named in the program's About box).

== Samples ==

Cover CDs for the Polish computer magazine ''Enter'' sometimes contained KCD catalogues of earlier discs from the magazine.

Examples include:
* Catalogue from the ''Enter'' December 1998 CD:
** [https://discmaster.textfiles.com/view/31717/ENTER12_1.iso/ARCHIWUM/zbior%20plyt%20enter%20cd.KCD hexadecimal view]
** [https://discmaster.textfiles.com/file/31717/ENTER12_1.iso/ARCHIWUM/zbior%20plyt%20enter%20cd.KCD download]
* Catalogue from the ''Enter'' January 2001 CD:
** [https://discmaster.textfiles.com/view/31697/0011272319.iso/Archiwum_CD/enter.KCD hexadecimal view]
** [https://discmaster.textfiles.com/view/31697/0011272319.iso/Archiwum_CD/enter.KCD download]

== KCE format ==

KatalogCD can also export databases to the '''.kce''' format, described in the help file as a "preferred data export format". The exact purpose of this format is unclear, but it appears to be intended for transferring data between individual .kcd databases. (In the shareware version, the import function seems to be disabled.)

KCE is a plain-text format consisting of a series of entries, each corresponding to an item in the database (a disc, folder, or file).

A specification of the file format (written in Polish) can be found in the [https://discmaster.textfiles.com/view/31727/EnterCD%202_2002.iso/Archiwum_CD/KAT_CD/KATCD.HLP KatalogCD help file] (see section: "Import z pliku KCE").

For example, the following .kce file specifies a simple database containing an entry for a single CD, with a single file stored in the path <code>/foo/bar/readme.txt</code>:
