Using File Commander, you can move and paste files and folders from and to your SD card on Android 7 or higher devices. To paste or rename a file or a folder, you will be asked to grant the app 'write' permissions.
- On the Hint window, tap OK.
- Tap the contextual menu in the top right, tap Show SD card.
- In the navigation drawer, select the top-level 'SD card', and not a sub-folder.
- Tap Grant write permissions or tap Allow.
