Cannot copy <filename> path is too deep

Hello,

I am experiencing this problem on a Windows 2003 R2 SP2 server, the
file/folder character length are less than 255.

The clients OS vary from Windows XP to Vista, if I am on my domain
controller and i try to move a big file to my storage server (the one
experiencing the problem) I get this error.
This is happening every time and to everyone, files can vary from 30MB onward.

Any idea why guys?

Are your drives NTFS formatted?

This is a Windows* OS/file system issue.The cause is directory paths on the drive is longer than 255 characters (including spaces).There's a lot of additional softwares which can fix this problem like Long Path Tool.
