The $AC file type is primarily associated with '$&Sense' by Monogram Software/Software Toolworks/The Learning Company. This is an old DOS accounting program. The program is no longer on the market and the company is no longer in busines. It was originally published by Monogram Software (1988) which was taken over by Software Toolworks which was renamed to Mindscape in 1994. Mindscape was absorbed into The Learning Company in 1998 and the program is no longer supported.
