long file names cant copy

hello experts I have about 10k files Im moving off one share to another, but windows explorer wont copy them because the names/path is too long. I found a hotfix on line but further research indicated it broke more stuff than it fixed so I was afraid to install that rollup.

Any suggestions on an easy way to rename/move these files ?

Last time I ran into this, I just mapped drives to the destination and source folders. Like X: and Y: - then just copied from one to the other.

I just tried your suggestion and still getting the same error message "the source file name is larger than supported by this file system"

Just use robocopy, preferably either on the source or target server; it doesn't have problems with long file names.
Example (note that the first argument is source folder, the second is the target folder, then the file mask):
robocopy.exe "D:\Data" "\\Server\Share\Data" *.* /e /copy:DAT /r:0 /np

Open in new window

If you want to copy with permissions, then instead of /copy:DAT, use either /copy:DATSOU, or /copyall.
For further options, enter "robocopy /?".

Use oBda's method. You will get all the data over with the long file paths.  


you want to go with  /s /e /copyall /v /tee /Log:c:\temp\copyreport.txt

the /v -will show you what files were skipped if any
the /tee will have output on your monitor as well as in the .txt file that I have redirected to that you can look at later.
/copyall will give you the acls, attributes, security, owner, and timestamps from the original source
/s -subdirectories
/e-empty directories

You may not need the quotation marks at all.  If it throws an error when you first run it just go with

robocopy \\sourceservername\C$\remainingpath\  \\destinationservername\C$\remainingpath\  /s /e /copyall /v /tee /log:c:\pathtoyourreportfile.txt
