Some files could not be migrated because you do not have access rights. Import the files you want to migrate from [Import PDF] in the [Preferences] screen.
- Cause
For Android 11 or later, along with the security enhancements that are made for the operating system, it is possible that access rights to the files have been lost.
- Solution
Import the files you want to migrate from the [Preferences] screen. For details, refer to Importing PDF Files (Android 11 or Later).
The files that were not migrated can be checked by tapping [Results of the file migration] in the message.
If some files were not migrated, the files can also be checked from [Results of the file migration] under [File Management] in the [Preferences] screen.
