I used Testdisk → Photorec via command terminal to recover files. It finished but now I can’t delete the recovered files I don’t need. If I try to delete the whole folder, it says “access denied”, if I try to delete a file inside the folder, it says “you don’t have permission to delete files…” I can’t change anything in the permission settings of the folder. It says owner is “root”. Any idea how I get rid of the files?
