Guest Snuffy Posted June 20, 2008 Posted June 20, 2008 Is there a method to disable users from compressing NTFS drives, folders, and/or files on a server? For example, if a user goes into properties for a network drive there is a check box option for "Compress drive to save disk space". If they check this option there are not denied access and the compression occurs. A couple users have already compressed their home folders. Luckily nobody has done this for the common shared folder yet. I played with this in the lab and it appears write access or higher allows a user to compress. This MS article says how compressing can affect performance so I find it odd it can't be easily disabled for users. "Best practices for NTFS compression in Windows" http://support.microsoft.com/kb/251186/EN-US/ I have done a lot of searching and have yet to find a good solution. I was hoping for a group policy method so it can be done centrally and quickly. This is the only possible solution I have found, 2 quotes from MS below. It would basically mean formatting the drive with a cluster size larger than 4 KB. I haven't tested this yet. I'm hoping there is a better way. "Because file compression is not supported on cluster sizes greater than 4 KB, the default NTFS cluster size for Windows Server 2003 never exceeds 4 KB." "The compression algorithms in NTFS support cluster sizes of up to 4 KB. When the cluster size is greater than 4 KB on an NTFS volume, none of the NTFS compression features are available." This is what I am working with. Client: Windows XP Server: Windows 2000 & 2003 Anyone familiar with this issue and its solution?

Guest Snuffy Posted June 23, 2008 Posted June 23, 2008 Re: Disable NTFS Compression for Users Thank you Meinolf. I did come across that during my search. I was hoping for a simpler, centralized method, but may end up using this or formatting with a larger than 4kb cluster size if nothing easier comes up. The distribution method and making sure all clients always have this may be a pain.
