Hello, I have a USB drive that is almost full so I am trying to move some of my files to my back-up. However, some of the folders/ files are "write-protected" and it won't let me copy or move them. I have no idea how some of the folders became write-protected while others did not. When I go into properties and unclick the "read-only" tab then apply it, the setting is not saved and it goes right back to read-only. It is letting me delete the folders, just not copy them. Unfortunately, quite a few of these files are only saved to my USB. Any help you can provide would be greatly appreciated. TIA!
