The only other ways I have heard to do this are:
Files App
Files by Marc Apps and software. Available on the Aurora Store
App allows access to the /android/data folder and can facilitate file transfers.
Does not need Google play services. Contains no trackers
Using Developer Options
- Enable Developer Options: Go to Settings > About phone and tap on Build number seven times to unlock Developer Options.
- Enable USB Debugging: In Settings > Developer options, enable USB debugging.
- Use ADB Commands: If you’re familiar with command-line tools, you can use ADB (Android Debug Bridge) to push files directly to the /android/data directory.
