[...] which looks to me like a bug, [...] CHANGES says that this was fixed in Zip version 3.1d03. Current development code (3.1e23) works correctly.

[...] requiring a minimum version of Zip 2.0 to extract ... however, I cannot seem to find this version existing anywhere, [...] So what? Which part of "minimum" is unclear to you? According to the APPNOTE: https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT Version Needed To Extract = 2.0 for an archive member means that one of the following features was used: File is a folder (directory) File is compressed using Deflate compression File is encrypted using traditional PKWARE encryption I...

Failure to properly handle archives with backward slashes under Linux

https://midnight-commander.org/ticket/4238 It's an upstream bug [...] Not on our tributary. It might be helpful if someone explained the actual situation in that other forum.

I need to apologize. Ok. unzip under Fedora 35 unpacks both archives with zero issues I can believe that. So, there's a bug: files in archive directories cannot be extracted by mask. Or, it's not a bug in UnZip, but you didn't treat "\" as a special character? Try "\\" instead of "\"? Using your other (smaller) example archive: proa$ ln -s ScreenRuler-v.0.8.1-Portable.zip SR.zip proa$ unzip -l SR.zip 'ScreenRuler-v.0.8.1-Portable\README.html' Archive: SR.zip Length Date Time Name --------- ----------...

The current behavior of UnZip (or Apple's Archive Utility app) makes some sense, [...] More than I had realized. I apologize. Initially, I was too lazy to do the extraction; I just looked at a listing ("unzip -l"), and saw the backslashes. "Trust no one," I always say. So, today, I actually did the work, and noticed that UnZip apparently already handles this situation, which my tired, old brain had forgotten. Around here, on a Mac, for example: proa$ mkdir SR proa$ cd SR proa$ unzip6 ../ScreenRuler-v.0.8.1-Portable.zip...

unzip [...] As always, a program version number would be helpful, but it probably doesn't matter much in this case. unzip -v [...] doesn't properly handle archives with backward slashes under Linux. I just ran into this problem in a Ford/Microsoft SYNC software update kit a few days ago. If you try to unpack any of them, you'll get funny results. That depends on your sense of humor. One could argue about what "properly" means in this case. Such archives do not conform to the zip archive standard,...
