Windowss XP - Is there a way to change the MAX_PATH value for pathname/filename?  I want to reduce it to 220 characters.

I have a problem accesssing user data that meets the 255 character limit when accessing it via DFS-Root. Adding the DFS-Root path to the file forces the the pathname to exceed 255 characters and can not be accessed or deleted and causes file recovery from shadow copy to fail.

Is there a Group Policy or Registry key I can set/modify?

Thanks.

No. The path length will differ, depending on how you access the file (UNC path, mapped drive, locally).
There is no general 255 character limit, by the way. The NTFS limit is around 32000 characters. It's only an *application* problem; if an application uses the old APIs to access files (and even Explorer.exe and Office 2003 still use them ...), it will indeed not be able to access any path longer than 255 characters. There's no way around this except to shorten the path either by renaming or by accessing it through a mapped drive that's pointing deeper into the folder structure.

That's what I thought. As you have correctly surmaized it is Word 2003 that is creating these long file names. I really find it hard to comprehend why Explorer does not support 32kb pathname as it is the driving force behind Windows. Try shutting down Explorer in Task Manager then try accessing your Desktop!
