I was wanting to clear up some room on my C: drive, so I moved the My Pictures folder (by right clicking and choosing to change location) to the root of my E: drive. The folder disappeared, and so I checked the photos library, and it said it was referring to E: Backup (the name of my drive) for the pictures. It was also treating the drive as my pictures folder. I right clicked on the drive, and told it to restore to default location. It moved all the files on my drive to a file named "Pictures" instead of "My Pictures" the file is also treated as a normal file with a normal file image. How do I get my computer to recognize it as the official pictures folder?
