550 process cannot access file it is being used by another process


trying to upload a .mdb and smartftp or my host cut the connection. The mdb file is up there, but file size is 0bytes, and I cant over write, rename or delete it as i get this message:

550 [filename].mdb: The process cannot access the file because it is being used by another process.

Ive had that before and usually leaving it for a minute or two solves the problem, only its been about an hour now.

Any ideas as to how to solve the problem gratefully received.



thanks very much for your help.
The file unfroze itself after about 4 hours, strangely, but I will bear that in mind for next time.
thanks again!
