Maximum share size in Windows 2003

I was reading an article by Gary Olsen on the techtarget.com site entitled "Leveraging DFS in Windows Server 2003 R2". In this article Gary states, "the administrator reported a performance problem on one site that had a 62 GB share size, which is close to Microsoft's recommended maximum of 65 GB." I have never seen any info on a recommended maximum share size from Microsoft. Is there a Microsoft article that states this? We have several shares here much larger than 65 GB and have not seen any issues, but we would like to verify this statement if possible. Thanks Dennis Ervin dervin@ci.lenexa.ks.us

Thanks. We'll let you know when a new response is added.

I have never seen a maximum share size either. I too have several very large shares with no performance problems. I would have assumed it would have been the NTFS maximum.

I have how ever, seen situations where the number of files in a single folder causes problems on windows when you try to view the folder in the gui and when you try to access (read or write) to the folder. My experience syats this definately happens at the 200,000 to 300,000 mark.

I to have never seen a problem with a large file share. I’ve got a couple of file shares with hundreds of Gigs of data in them. The key I think is the number of files in each folder. We keep the number of files per folder small (it’s an automated system so the files always go into dated folders) so we never really have a problem with slow performance.

We have on older share which has a lot of folders at the root of the share, and it takes a while to load up, but again we think it’s because of the number of objects. The sub folders all open very quickly when accessed.

    He is NOT referring to a share in the meaning that I think you’re referring to. He is discussing Distributed File System. This like give an overview http://technet2.microsoft.com/windowsserver/en/library/d3afe6ee-3083-4950-a093-8ab748651b761033.mspx?mfr=true When you do DFS, you need to take into consideration the size of the data. IF you are talking about a pure folder share and NOT DFS, they I believe you are correct that there is NO share size limit.
