RoboCopy Issue

I have been using xcopy to copy data from a file server to a flash drive. That works OK, but after some time the flash drive is cluttered with files and folders that have been moved or deleted from the file server.

I want the flash drive to mirror what is on the file server, so I decided to give ROBOCOPY a try (version XP010 on a Windows XP computer). Here is the line in my batch file:

ROBOCOPY \\fileserver\share\frank\somefolder E:\somefolder /COPYALL /B /MIR /R:0 /W:0 /LOG:MyLogfile.txt

This works fine except the log file reports Error 3 "The system cannot find the path specified" for files in only one subfolder, and deletes all the files in that subfolder from the flash drive.

The subfolder name is "Computer" (which as far are I know isn't a reserved name), and it has the same attributes and NTFS permissions as all of the others.

Any ideas what the problem could be?

 

Noone uses Robocopy?
