AIN

AIN is a 1990s DOS compression/archival format, apparently produced by a shareware program of the same name. Not much information is available on it, beyond what has already been stated (which is to be found on several copying-from-each other "format information" sites   ). The webpage of a format identification program links its name to the list of software produced by a since-defunct company called "MicroFox" ; however, the only compression utility listed there, called "PUT" (the decompressor being called "GET"), writes to files with the extension .put, in an extant copy, and is listed separately on the identification software webpage.
