I have a text file in a compressed file (RAR/ZIP). On my desktop, I happen to be able to edit it, and then WinRAR or 7-Zip sends a message saying the text file was changed and asking if I want to update it.

The same thing seems impossible to do in Android 8.1.0. I have tried ZArchiver, ZArchiver Pro, RAR from Rarlab, and several text editors, but in the end, the zip file is never updated with the changes I make in the text.

I also tried MiXplorer and MiX Archive (the archive plugin), and although it's a powerful tool, it's not working. When I try to save the text file, it says "Not supported!" regardless of the zip or rar file. I wonder if it's because the archive has a password. It also seems it can't open the zip file directly from the Dropbox app, providing the same "not supported!" error.

Does anyone know a way? Or a way that allows me to set a password on a text file that is cross-platform between Android and Windows? Any hint, or any other tool I could try? In the settings of MiXplorer, it doesn't seem anything could help.

You can't just "edit" an entry in-place in a RAR/ZIP file because it's compressed.

You'll need to decompress it, edit the files as needed, and then re-compress it.

WinRAR (Windows) do this steps automatically. Up to now, I couldn't find an application do like WinRAR (Windows) on Android OS.

  • I beg to differ here slightly...I tested the feature with mixplorer and it works, but your reasoning is pretty much correct, this operation is simply not supported 'out of the box'

  • Are you sure MiXplorer do it without decompressing? I think because of built-in text editor, it were worked.

    Pretty sure, I reckon it does it the same way as Winrar on Windows does, the process may be 'automatic' but essentially you don't manually decompress the file

    @xavier_fakerat Actually, the answerer is right. The only difference between the app you mention is that it hides the unpacking and repacking procedures to the user. Edit: granted, you don't manually decompress anything, as the program handles everything.
