Guest Bart Perrier Posted June 4, 2008 Posted June 4, 2008 We are getting ready to migrate about 1000 Home Directories to a new location on the network and I have my strategy/plan ready to go but I have been noticing something that I am hoping I can get around. I have some users who are very, very organized and very beautifully create folders with excellent names for everything. The problem is, eventually the complete path of the folder, even with a mapped letter drive, becomes too long. What is the character limitation for the path to a file? I was under the impression is was a lot longer than a user could conceivably exhaust, but I am mistaken. Below is an example -- I have removed the username and replaced it wtih NAME01. It is 326 characters long. Thanks.

If his share points into the middle of a long path (e.g. d:\Users\NAME01\Audits\FY2008 Audits\2007-06 Lab MCR Compliance Review) then the physical length as seen on the server can be much greater. You need to educate your users to put their information into their files, not into their folder names. Paper-based suspension files used to have tabs and people got along very nicely with the small amount of text they could write on these tabs, so ask your users to stick to this principle.

Guest Meinolf Weber Posted June 5, 2008 Posted June 5, 2008 Re: File Path Limitations Hello Bart, Small remark, today i got a dvd with a lot files without a document type like .doc or whatever, which i found out after copying them to the harddrive with robocopy (windows drag and drop itself was crying about corrupt files). After determining the corrupt files in a more then 255 character based folder structure + filename, which contains the content of the document, i had problems to delete this files. Because of no endings like .doc or whatever, i could not rename or add an extension, nothing. The disk was from another company built and finally i found a way to delete the corrupt files, but it took me longer then planned for this. In our offices we teache the user's about this, over years ofcourse, but it helps.

I have not thoroughly explored RoboCopy but do have a strategy that I am familiar with -- I will do a full restore (about 5 hours -- 200 GB) during the week and then a final incremental backup after i break the share. My mock testing has indicated this will take me about 2.5 - 3 hours total on the night of go live. Fortunately, that is will within my window of availablity. We have 5000 plus users of which about 2000 use home directories, but we don't have a good training plan for the windows side of things as office folks are hired. Ironically enough, our users have not notified us of a problem, yet I have noticed it in my testing. 5,000 users = 10,000 opinions, all subject to change after sleep. Thanks, again, for the replies.

Guest James Posted August 6, 2008 Posted August 6, 2008 Re: File Path Limitations Hi, I am aware of 256 characters path limit in naming a file, but can you help me how to limit the path for file naming to 240 characters only? is there a way to limit that in registry editor or is there a way to group policy (if so, pls. show me), we are using windows xp pro as our client pc and windows server 2003 std edtn R2 as our server. your help is very much appreciated Thanks, James "Bart Perrier" wrote: > > "Meinolf Weber" <meiweb(nospam)@gmx.de> wrote in message > news:ff16fb669f65e8ca9576cb6fb030@msnews.microsoft.com... > > Hello Bart, > > > > Small remark, today i got a dvd with a lot files without a document type > > like .doc or whatever, which i found out after copying them to the > > harddrive with robocopy (windows drag and drop itself was crying about > > corrupt files).
