Add support for Microsoft Compress archives #301

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm not sure if Microsoft Compress archives work, but these sure don't:

http://cd.textfiles.com/gw2k42/WFW311/

The compressed files have extensions ending with _ . Expand.exe (also in that 
directory) is normally used to extract them.

mscompress from ftp://ftp.penguin.cz/pub/users/mhi/mscompress is supposed to 
work but doesn't appear to.

Yeah, these seem to be entirely unsupported. This should definitely be fixed.

The first four bytes of the file header (KWAJ) lead me to this:

From the header it looks like compression method 3, a combination of LZ and 
huffman.

This library looks like it can handle the samples:

Update:
I compiled libmspack and the included test program "extract" was able to 
decompress the files.
