Total Commander

I have a zip file created by DropBox, as it does when you download an entire folder and contents.

I know how to unzip the ZIP in TC, but after the file copy operations are done, the results are not where they should be! I have tried different destination folders with the same results. It's as if nothing happens (though the thermometers show rapid progress).

Android 10 on a Samsung phone.

Can you give me more information on how you created that zip file? It works fine in my tests. Here is what I tried:
I went to www.dropbox.com and downloaded two folders, each to its own zip. Then I tried unpacking them with Total Commander:
1. Went to target directory in one panel
2. Swiped sideways to the other
3. Opened the zip
4. Selected the folder
5. Pressed the Copy button, and then "COPY"
Result: All folders and files were unpacked correctly.

Second method:
1. Went to target directory in one panel
2. Swiped sideways to the other
3. Selected all the zips
4. Long click -> context menu
5. Unpack all selected
6. UNPACK (TO TARGET PANEL)
Result: All folders and files were unpacked correctly.
