Page Defrag is a tiny 70 Kilobyte software that displays information about how fragmented your paging files and registry hives are. Defragmenters running in Windows have no way of defragmenting those paging files and registry hives which usually means that they get fragmented over time which can degrade system performance.

Page Defrag can defragment all files open for exclusive access at the next system boot or even at every boot. Information about the process and results are printed directly on screen which is excellent to see if the defragmentation was successful or if any errors occurred doing so.

You can naturally run Page Defrag again in Windows to check the defragmentation level of those files as well. It is not necessary to us the software if your defragmentation tool offers this option as well.

Please note that PageDefrag is only compatible with Windows XP (32-bit) and Windows Server 2003 (32-bit), and not newer versions of the Microsoft Windows operating system.

Please note that it will take the operating system longer to boot whenever the defragmentation process is run on startup of the system. PageDefrag prints the file name and status of each file that it is processing on boot, and if it is successful at reducing the fragmentation of a file, the number of clusters a file started with and the number of clusters of a file after the process.

The developers have added command line options to the program, so that you can theoretically launch it from batch files as well or systems that boot to the command line. The basic usage is pagedefrag followed by the following commands:

  • -e defrag on every boot
  • -o defrag on next boot
  • -n never defrag
  • -t set countdown to number of seconds
