I have encrypted some files with 7zip on Windows 10.
I used therefore ULTRA compression LZMA2 method, 64MB Dictionary size, 64 Word size, 4GB Block size, AES256 encryption method and I encrypted the filenames.
Of course 7zip works reliable on Windows for years and the *.7z archive file is valid and can be opened with 7zip on Windows.
After copying the .7z archive file to Android 13 smartphone I tried several Apps over there which promise to be able to handle 7z file.
But I couldn't open the windows *.7z archive file
All the Apps (and file managers) tell me something about "encryption not recognized " or similar.
Whats wrong?
Whats a recommended APP for opening *.7z file with the parameters from above?
Maybe this is possible only if I change the parameters from above.
e.g. compression method?
For me its important that filenames inside a *.7z archive are password protected too.
So the Android App should at least be able to prompt for password when I try to view the content of a *.7z file.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
