UltraCompressor II (UC2) is a 1990s-era compression and archiving program for the PC platform (DOS, Windows, OS/2, DesqView) which claimed to be both faster and more compact than other compression systems. It had special support for OS/2 extended attributes. It was a commercial program released as a "try-before-you-buy" download. It was developed by Ad Infinitum Programs (AIP-NL).

[edit] UC2SEA
Some versions (the Pro versions?) of UC2 include UC2SEA, a utility for making self-extracting UC2 archives.
[edit] UCEXE
Some versions (the Pro versions?) of UC2 include UCEXE, an executable compression utility. It can compress (at least) DOS EXE files, and COM files (converting them to EXE).
[edit] Identification
UC2 archives start with ASCII "UC2", followed 0x1a.
A likely signature for both UC2SEA and UCEXE formats is "UC2X" at offset 28.
[edit] Software
Note that a designation like "UltraCompressor II revision 3" is roughly the same as "UltraCompressor version 2.3".
