> Has anyone ever used .exe for anything other than Windows?

Did you know that Microsoft Windows originally ran on top of the much older MS-DOS, which used EXE files as one of its two executable formats? Most Windows users had lots and lots of EXE files which were not Windows executables, but instead DOS executables. And then came Windows 95, which introduced 32-bit Windows executables, but kept the same file extension as 16-bit Windows executables and 16-bit DOS executables.
