A folder named 20575407c5cd8d0434 has appeared on the 'C' HDD. When deleting
get the: Folder access denied - You need permission to perform this action
You require permission from S-1-5-21-1409082233-1547161642-725345543-1004 to
make changes to this folder.
Never seen anything like that before. Any help appreciated.
