when I am trying to delete *some* files (movies..) on my galaxy Tab S2 microSD .. I keep getting "task failed" or alike .. I have tried half a dozen file managers .. reboot .. safe mode .. but I can delete them fine on my laptop! I am thinking its got to be some file permissions issue .. there has got to be some program that will let me reset all file permission on my microSD card or some solution? please help .. thank you ..
