I moved some of my libraries to my third storage drive, now I want to delete the original. But here's the thing, since the originals were made I've reinstalled Windows. I didn't get rid of the original files when I did that, because they were on their own drive (which allowed me to easily set Windows up again without deleting everything), but now I want to get rid of those folders I cannot do it, because permissions are still with the old Windows install

For some reason, the old turn it off and on again worked o_O. I'm pretty sure those files were not created under this install (or perhaps they were, depending on when I re-set this up)

It was definitely saying access denied though and that I need permission from 'bunch of numbers and letters' indicating that account no longer existed
