Encrpyted ZIP will not unzip in Windows

[NMM2]

Hi,

I encrypt a file with ZIP within TC 2.72 (Android), then copy the file to a Windows-Computer an want to decroypt it, but it always claims, that the password is wrong.
If I decrypt within android itself, the decryption works fine.

I tried with different passwords, but its always the same: in Windows I cannot decrypt.

What is my mistake in this procedure?

Regards
MM

Do not confirm.

The same version of TC4A from Play Store, archivation parameters here and here - can unpack it w/o problems both on desktop and Android.

Test file is here, p/w:[/face]

Code: Select all

TotalCommander

... then copy the file to a Windows-Computer

How did you copy the file?
If you are using FTP, it is important to use binary mode (not text, not auto).

This happens when you pack files to Android 6 external storage (e.g. USB sticks or secondary storage). The problem is that it's not possible to random-write to such files, they can only be written linearly from start to finish. I have to use a special format for this which TC for Windows can't yet unpack (but which follows the ZIP standard).

You will either have to use a different unpacker on Windows, or create the ZIP in the internal memory (usually /storage/emulated/0) when using encryption. TC9 will support the format.
