I want to copy .wav sounds from my SD reader to my USB drive but it doesn't seem to work. It does work with Windows with the same devices and files.
Error code: Error opening file “/media/filessamplesfs/b471cde8-2a15-44e7-acce-e9a2a54511a6/padio/th06_01.wav”: Access Denied
Ubuntu version: 18.04
UPDATE: Stopped working on Windows. I tried it on another computer and the files were gone.
