My findings (using winzip 8.0 on Windoze 2000):Hmm. 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). crunch1.dsk.gz ... 119,675 bytes ... Path=c:\Apache\Apache\htdocs\crunch\ ... FAILED: "Could not create C:\Temp\c: - aborting extract operation." <<== NOTE problem with c: in path crunch2.dsk.gz ... 113,728 bytes ...

FAILED: "Could not create C:\Temp\c: - aborting extract operation." <<== NOTE problem with c: in path 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.
