it actually seems like Fossify File Manager is reading the ZIP file incorrectly in the prepatory stage: compare these two screenshots from Fossify and from Samsung File Manager.

Can you send a sample file? I just tested various ZIP files, and unpacking works correctly.

[nehemiagurl]

I can reproduce only with two specific ZIP files neither of which are meant for general distribution. Do you have access to the [email protected] email address? I can send them there.

[Aga-C]

Please send it there, we will check it.

Thanks for sending! I've confirmed, and in fact that ZIP doesn't work in File Manager. 

From a quick search, it looks like we've inherited that bug from zip4j library: https://github.com/srikanth-lingala/zip4j/issues/135.

Interestingly, unzipping .zip downloads from Amazon Music worked for me when I first got the app, but unzipping my own .zip folders or those created by colleagues does not work at all. One of the reasons why I got the Fossify app for my Fairphone was that I was hoping it would handle ZIP. Is there any recommendation on what other apps to install while ZIP isn't working in the File Manager?

[nehemiagurl]

idk if it's just that I haven't received any files created that way or that upstream solved the issue, but it hasn't been recurring for a while now.

I was testing https://pairdrop.net and tried to send multiple files between devices. Had the same problem as highlighted here, the preview only shows a single file and an error is reported when extraction is attempted. Attaching the file I sent myself along with screenshots of the fossify file manager and built in one.
