FOXSQZ

Latest revision as of 02:58, 14 June 2024

FOXSQZ is a compression library, and associated .SQZ compressed archive format. It was developed by Master Creative Software. It is designed to work with the FoxPro database software.

Some distributions of FOXSQZ include FOXSQZ.EXE, a command-line utility for DOS. Others do not.

[edit] Format details

FOXSQZ supports at least two compression schemes.

The "Max" compression scheme is based on PKWARE DCL Implode, but modified in some way (segmented?).

The "Fast" compression scheme hasn't been evaluated.

[edit] Examples

Here are some examples of using the command-line utility.

To list contents:

FOXSQZ L EXAMPLE.SQZ

To extract files:

FOXSQZ U EXAMPLE.SQZ

To create an archive, "Fast" compression:

FOXSQZ SCF EXAMPLE.SQZ FILE1...

To create an archive, "Max" compression:

FOXSQZ SCM EXAMPLE.SQZ FILE1...

[edit] Identification

SQZ files created by the command-line utility start with ASCII "FOXSQZ COMPRESSED FILE", followed by bytes 0x00 0x1a.
