Android zip64 issue with compression level 0

[tomix89]

I'm developing a website which can generate >4GB zip files to download. These zip files are using the zip64 extension (zip v4.5) and are created on the fly, e.g. streamed (also known as having a descriptor). These zips are in store only (no compression) mode. I'm able to open these zips by for example built in windows 11 unzip tool, built in Ubuntu 22.04 unzip tool, 7zip windows, also on Android 12 (Samsung Glaxy A41) with the built in unzipper.
Total commander on windows seems to handle my zips also correctly.
Now Total commander android is able to open the zip (so i see the list of files inside the zip), but when i try to unpack this zip, the progress bar freezes on around 20% of progress.

What i'm zipping is a single 5GB file.

I originally thought it might be this streaming aspect, but it turned out it might be an actual bug in TC ?
I dig further, and when i try to zip this 5GB single file on my phone with TC and i select a compression greater than 0, it seems to have no issue. But once i set compression to 0 (e.g. no compression) it does the same freeze of the progres bar on around 20%.

So i would say we have a problem with zip64 + compression 0 only on android ?

I used TC mobile 3.61
Unfortunatley i'm unable to create a compressed zip from our website, and i was inable to find any other site that does zip64 + steram + store only.

Thank you, and keep up the great work!

Thanks for your report, I can confirm the problem. The function to unpack stored files used a 32-bit variable in one location, which stopped the unpacking. I will release a new version to the beta channel as soon as possible.

This should be fixed in Total Commander 3.62 beta 1. Please test it!
