I have a 3tb internal drive that is used for backup. It consists of one folder (labeled 01) that has around 200 folders of backup files. In the past if I copied a file from another drive to one of those 200 folders, and then decided to copy another file to another of the 200 folders I could expend the parent folder and choose a different folder. Now, however, if I choose to copy another file the only folder that is available to me is the previous one I copied to. To make things stranger, if I make another folder titled 02 in the main folder structure with the 01 folder then I am able to expand the folders on subsequent copies. If I hide that 02 folder or delete it, it goes back to where I can't copy but to that one folder I chose. Any one have any idea what would be causing this? It's just recently started happening, and doesn't happen on any other folders on my other hard drives. Thanks in advance for any help!
