I installed Primitive ftpd 6.11 on a tablet with Android 11. I want to back up the Android files to another server using a sync script.
I select SAF storage. It opens the Android file picker. Whether I select the root of the internal filesystem, or the root of sdcard, the picker says “Can’t use this folder”
Presumably I could create a new folder, but that is not helpful.
The whole point is to back up the file system, not one specific folder.
Is there a workaround, or is the SAF unusable for this purpose?
I read that Android offers Manage All Files Access for this purpose, but it appears to need to be part of the app.
