TINYPROG is an executable compression utility for DOS, developed by Tranzoa. It compresses EXE files (to EXE), and COM files (converting them to EXE).

It has several options that affect the compressed file, including a password protection feature.

Identification

According to the documentation, a compressed EXE file has bytes 't' 'z' at offset 28. The next byte is "hex C0, logically OR'ed with the TINYPROG version number".

TINYPROG-compressed files normally contain the following ASCII string somewhere in them:

TINYPROG says, "Bad program file!"

Except that password-protected files instead contain:

TINYPROG says, "Bad password or program file!"
