Cannot Delete Folder on my FTP

[Casey Milano]

We have had this problem several times before: I try to delete a folder that we no longer need but it doesn't work. I can usually delete the contents of the folder, but the actual folder cannot be removed or even renamed. This is the message I get when I try to delete the folder:
Command: RMD (!) Mecum Monterey - Daytona Coupe Sells for $7.25 Mil
Response: 550 (!) Mecum Monterey - Daytona Coupe Sells for $7.25 Mil: The process cannot access the file because it is being used by another process.
Status: Retrieving directory listing...

The error message comes from the server.

You need to contact the server administrator.
