'''AIN''' is a 1990s [[DOS]] compression/archival format, apparently produced by a shareware program of the same name.

AIN is a compressed archive format, produced by a DOS shareware program of the same name. It was developed by Transas Marine Ltd.

Contents

AINEXE

AIN also includes an executable compression utility named AINEXE. It compresses MS-DOS EXE files.

Self-extracting AIN archives?

The AIN software was distributed in what seems to be a "self-extracting AIN archive", and the file command agrees that that is a thing. But we haven't seen any evidence of a publicly-available program or feature for creating such files.

Notes

The documentation says "AIN version 2.21 archive format is incompatible with that of AIN version 2.0."

Identification

At least some .AIN files start with the byte sequence (hex) 21 ?? 00 00 00 00 00 00.

AINEXE-compressed EXE files most likely have ASCII "AIN" at offset 32.
