In my case I had 4 ZIP files as part of a Split (sometimes called Span) that had been moved from floppy disk to a DVD and renamed. This made it impossible form Windows EXTRACT or WinZip or 7Zip to figure out which file was which.
The file names were:
Each file was 1.4MB (except the #4) which lead me to think they were really a single .ZIP file that had originally been spanned/split over 4 floppy disks. The naming convention for split/spanned zip files is FILENAME.Z0# so I renamed them to:
The last .ZIP should be .ZIP and it contains the index for all of the previous disks/Zips’ so that one you should not rename.
WinZip, 7Zip and Windows Extract still could not open them when I launched LOCAL_REPORTS4.zip. I would see errors like:
The remainder of the solution was to use WinZip’s command line tool which I sourced from HERE. I followed the general repair command line instructions from WinZip support which lead to trial and error file renaming exercise. When I ran the command:
c:\Program Files (x86)\WinZip>wzzip -yfs “c:\2004\LOCAL_REPORTS4.zip”
I would see an error like:
The disk you inserted appears to be disk 1, the requested disk was 3.
and that gave the clue that the file I had named 3 I should rename to 1. After renaming files based on what the error said, I was eventually able to extract all of the files.
