At least one hundred readers (yes, seriously) wrote in to tell me that the latest version of Diskeeper, 4.0, does indeed offer the ability to defrag the Windows NT paging file. Diskeeper 4.0, which was released in late October, does cost about $50 for the Workstation edition and $250 for the Server version, however. In any event, it's a fine enough product (I'm using 3.0) that Microsoft is integrating it into Windows 2000. For more information, please visit the Diskeeper Web site
