MSG Files

On OS/2 there are several MSG files, these are referred as "message files".

If you open any MSG file with a text editor, you will notice that the file starts with "MKMSGF".

These files are generated with the MKMSGF program. There is also a clone of this program called mkmsgf-110.zip

There is also this program that "decompiles" MKMSGF MSG files called e_msgf_2005-05-10.zip
