--------A-MS COMPRESS 5.0-G-----------------
Microsoft ships its files compressed with COMPRESS.EXE, for expansion
the program EXPAND.EXE (how original ;) ) is used. The program
EXPAND.EXE is available with every copy of MS-DOS 5.0+, the program
COMPRESS.EXE is available with several development kits, I found it with
Borland Pascal 7.0. The compression seems to be some kind of
LZ-Compression, as the fully compatible? LZCopy command under Windows
can decompress the same files. This compression feature seems to be
available on all DOS-PCs.
