--Solution (3)--
1-Right click the file or folder > Go to > properties.
2-Click the Security tab. Under Groups or user names you will probably see a string of number/special characters. If you do not see something abnormal, this will not help you. If you do, click edit, click the abnormal object (in my case it was 875-d$d) then click remove. This should then allow you to delete/edit/move the file/folder.
I hope from these 3 methods 1 can hopefully help you.
Remember you must do & follow the --Solution (1)-- before doing/following other 2 solutions.
