- Short: Sources of SZDD xfdmaster client
- Author: Kyzer/CSG <kyzer@4u.net>
- Uploader: Kyzer/CSG <kyzer@4u.net>
- Type: dev/src
- Requires: util/pack/xfdmaster.lha
-
- This is the source code of XFD's SZDD slave, for the curious.
-
- SZDD is an incredibly weak LZSS compressor, which was used by Microsoft for
- many years in their installation software - all those files with a letter
- taken from the end of their extension, eg HELLO.EX_
-
- Thankfully, one day Johnathan Forbes decided to work for Microsoft, and
- happened to sell them his LZX compression technology, which is state of the
- art as far as LZH is concern. So now Microsoft use LZX compression in their
- installation archives, now under the guise of "CAB" files (I'm working on a
- CAB slave for xadmaster).
-
- This SZDD slave has only been tested on a few files, so it may not be
- entirely perfect. If you have a file it can't extract, please send it to
- me.
-
- Note that this slave does not support 'KWAJ' files, which replaced SZDD as
- the secret undocumented piss-poor compression format in the 1996 Microsoft
- Setup Toolkit. If you have an actual algorithim for this format (or are a
- skilled Windows programmer and could hack it out of MSINSSTF.DLL), please
- contact me.
