Note that the windows implementation of zip/unzip does not always return the original file contents after a round trip. Yes, I’ve seen it myself. That’s an even more serious bug, but it’s been there since win7 at least. I don’t trust the builtin zip at all.
- lfam 8y agoDo you have any links to bug reports or other documentation about this?
- pletnes 8y agoUnfortunately no. I experienced it when running software signed/hashed and it just would not run. The dev told me that this was well known and that I should not use the builtin zip. Sure enough, unzipping the file with 7zip worked like a charm. I’ve found the same when downloading a proprietary lib that would not link with a C/Fortran application. The devs there tracked it down to the windows zip being used to pack the file, which they did not normally do. So, just hearsay, but I’ve never even dreamed of bothering to file a bug report with microsoft. Is that even doable?
