For OS security reasons, the file was not able to be deleted using this application but was cleared from the file list only. Use another file management application to delete the file.

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 file have been lost.

Solution
The file was deleted from the [File List] screen, but it was not deleted from the mobile device so it still remains on the device.

To delete the file from the mobile device, use a file management application.
