This FREE utility allows you to defragment files in just a couple of mouse clicks in Windows Explorer. DefragMentor Lite implements a friendly user interface and contains a boot-time component, which allows defragmenting system files (e.g. registry and paging files) when the computer is booting up.

Even if you defragment the entire disk on a regular basis, some frequently changed files become fragmented long before the next launch of disk defragmenter. So you can use DefragMentor Lite to optimize placement of individual files thus reducing access time and improving overall performance of your system. Database files of any kind (especially large ones) are the best example of what DefragMentor Lite can optimize.

Due to the fact that some files are always locked by the operation system (e.g. registry and paging files), you cannot defragment them while the system is up and running. The Boot-Time Defragmenting feature of DefragMentor Lite allows you to defragment files of this kind during the system boot process before files get locked. Obviously, you have to reboot the system from time to time in order to give DefragMentor Lite a chance to run at boot-time.

Safety
DefragMentor Lite uses native Windows defragmentation routines and does not access the disk directly. When trying to optimize a target file DefragMentor Lite does not affect other files on the disk. Therefore, DefragMentor Lite is quite safe and cannot break the consistency of the disk data structure.

System Requirements
DefragMentor Lite can be installed on any computer running Windows 2003, Windows XP or Windows 2000. If you want to use the product with Windows NT 4.0 make sure Service Pack 2 and Internet Explorer 5.0 or higher are installed.

With DefragMentor Lite you can defragment files on disks formatted in FAT, FAT32 and NTFS file systems with cluster size less than or equal to 4K.

To use DefragMentor Lite you must be a member of local Administrators group on the computer where the product is installed.
