MC cannot properly unpack some ZIP file (example attached). The archive structure is recreated properly, but the contents are lost.
On the screenshot you can see unpacked folder in left panel and original folder contents viewable by click in the right.
I also
encounter the error when unpacking via built-in Windows unzipper, and they say Windows doesn't recognize some ZIP algorithms properly. If you use built-in Windows ZIP-engine (which is a bad decision of course), you should at least throw an error to user that archive was not properly extracted, but not silently unpack the empty folder.
7zip unpacks this file properly, so it's better to use its engine.
