GAUP incorrect output for Microsoft SZDD

I encountered a problem with file decompression with Total Commander. The Canon scanner driver that I tried to modify failed to function fully. I do have a few plugins installed. I managed to narrow down the issue to the Game Archive Unpacker plugin.

GAUP appears to handle the Microsoft SZDD archive format. But in some instances it may produce incorrect output, different from EXPAND.EXE, 7-Zip, or that built into the Windows device manager. I can't tell whether the archives were invalid to begin with.

A small sample is included, with the compressed file (*.da_), one created with Total Commander (*.daX), and one produced by Windows (*.dat).

The plugin appears to be discontinued, and there is only an e-mail address on the author's site.

Did you try to contact the author? Maybe the Microsoft format differs from the game format?

No, both use the same format. And I can confirm the issue with GAUP. Chances to get a response from the plugin author are pretty slim though, as already noticed the plugin is on hiatus since more than 4 years meanwhile.

You can move GAUP wincmd.ini entry at the end of plugin list to lower its priority if another packer is able to handle this archive type.

I have GAUP and Total7zip installed (Total7zip is registered above GAUP),

Ctrl+PgDn on cnq4808.da_ opens it with Total7zip;
Ctrl+PgDn on cnq4808.dat shows an error message (unsupported archive);
Ctrl+PgDn does nothing with cnq4808.daX.

Both the .dat and .daX file represent the decompressed data derived from the .da_ file and do not contain any archiver data which could be further expanded.

Well, in my case TC extracts exact copy of cnq4808.dat from archive cnq4808.da_. Total7zip uses 7-Zip so does it right.

There were some other troubles with GAUP so it is not the first its bug.

I will check out Total7zip. Maybe it will replace my current 7zip plugin, which also has some problems.
