Total Commander

If i want copy or move files from android/data to external or internal sdcard it ask me to remount to rw. But it is rw.
If i click ok to remount that solve not the issue.

If i use the inbuilt file manager it works perfectly.

I am using the latest beta 3.40b2.

System Aosp Android 12 with root.

android/data is a protected folder on Android 12. You probably can't bypass it with root. The builtin file manager isn't restricted as third party apps are.

Try denying Total Commander root rights to access android/data, it should allow access via storage access framework (virtual folders).
