I had a folder, not related to any program or installation that I made myself. It wouldn't delete for anything; kept telling me the folder didn't exist in its location. I could put things into it, rename it, but not delete it.
I tried software that granted administrative rights, software that unlocks files, ran CCleaner, Defragged, ran Microsoft Fix Its, ran SFC /ScanNow, tried rebooting, other invalid file deletion software wouldn't touch it because they don't delete folders, but Secure Eraser got rid of it.
