SYMPTOMS

If you upload a large file to an FTP server, and you try to rename the file immediately, you may receive the following error message:

550 The process cannot access the file because it is being used by another process.

The following entries are logged in the Microsoft Internet Information Services (IIS) log:

08:19:47 65.53.232.91 [4]RNFR myfile.zip 350 0 08:19:47 65.53.232.91 [4]RNTO myfile.zip.ftp 550 32
08:19:47 65.53.232.91 [4]QUIT - 550 0
08:19:47 65.53.232.91 [4]created /myfile.zip 226 0

CAUSE

This problem occurs because the first step in the rename process, RNFR (Rename From), for the Myfile.zip file starts before the put (or create) action of the Myfile.zip file is complete.
