Hi Roshan,

This happens usually when you are trying to copy files from NFS fileshare to Windows which has a character limit on filenames.

"The Windows API has a logical limit of around 255 characters and the behaviour of the described problem is consistent with this."

How long can a file name be?   

It depends on the length of the complete path to the file (such as C:\Program Files\filename.txt). Windows limits a single path to 260 characters. This is why you might occasionally get an error when copying a file with a very long file name to a location that has a longer path than the file's original location.

Workarounds:

You can use some tool like copy, xcopy or something to rename the destination file before it gets copied.

How are you currently copying the files.

You can try Robocopy:

The Robocopy command line utility, which is natively deployed with Server 2008 and server 2012, will overcome the Windows API limit and allow the copying of files / folder paths longer than 255 characters.

A sample command is included below:

robocopy SOURCE(MountPoint) DESTINATION(Production data path) /E /ZB /COPYALL /DCOPY:DAT /log:C:\LOG.TXT /NJH /TEE

 

Explanation of Robocopy switches

/E to copy everything including empty folders
/ZB to copy files in restartable mode (to survice a network glitch), then if it fails uses backup mode
/COPYALL copies everything including ACLs
/DCOPY:DAT copies all directory information including timestamps and attributes
/LOG:C:\log.txt outputs all information into a log file
/NJH hides the job header
/TEE also outputs to the screen

Hi Roshan,

I'm using Long Path Tool for these kind of problems
