Hmm.

Results with various archivers (under Ecks-Pee) on the gzip files:

Win-GZ: treats the file as uncompressed data and tries to compress it
- does not recognize that it's a gzip file.
gunzip for MS-DOS: "gunzip: crunch1.dsk.gz: not in gzip format"

What am I missing here?


Is the file size 119,675 bytes?

-uso.

My findings (using winzip 8.0 on Windoze 2000):
Winzip was able to successfully open each zipped file into its window for viewing the contents. I had problems extracting some of the .dsk images but not others (using drag and drop from Winzip window to Explorer window).

So they are definitely all zipped files ( < 143,360 bytes), not disk images with a misleading .gz file extension. The drag-and-drop extraction apparently tried to append the original path to my temp directory path, creating a syntax error.

When I used the 'Extract' toolbar button and made sure 'Use folder names' was unchecked, all the disk images extracted nicely. I can see I'm going to be playing games for the next several hours.

I didn't think the gzip I was using put filenames into the files. If so, there's definitely a bug in it for not treating \ correctly. :(

I'm re-gzipping them now. Though command-line gzip will generally ignore the filename stored in the file (if there is one) unless you tell it otherwise.
