Until you discover the cause of your problem, try opening your Folder and
delete the files then delete the empty Folder. This may seem to be a sloppy
way to get it done but I've had to do just that when I was pressed for time.
I am the administrator on my computer, but sometimes I have trouble getting
"Permission" to delete a Folder when I'm working with Folders and files from
an external HD that were created on my other computers.
