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).

UC2SEA
Some versions (the Pro versions?) of UC2 include UC2SEA, a utility for making self-extracting UC2 archives.
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).
Identification
UC2 archives start with ASCII "UC2", followed 0x1a.
A likely signature for both UC2SEA and UCEXE formats is "UC2X" at offset 28.
Software
Note that a designation like "UltraCompressor II revision 3" is roughly the same as "UltraCompressor version 2.3".
