Hey - thank you - at first glance, this seems to be working. I'm currently restoring photos from the ___N360_BACKUP folder on my C drive and there are about 87,000 files, so it's going to take all day. I should have just restored a few, but will check back tonight when I get home to see what happens. I get the feeling that I might have backups within the backups on all of the backup folders and am hopeful I might discover I had redundant copies of the files I ended up deleting when I originally accidentally deleted the one N360_BACKUP folder.
Another possibility is the hard drive from which the deleted files came, which was in my former PC - a Dell Precision 380. I've tried to install in in my XPS 8300, but it's not being recognized and I'm sure I did it incorrectly. I might end up buying an external enclosure and seeing what I can find.
I will check back later when I get home to update what I've found and let you know. Thank you all for your help!
