Paragon Total Defrag 2010 doesn't object if your hard drive is almost full, either. While other defrag tools demand anything up to 10% free space, this one works happily even if you've only 1% available. And because the program can run before your PC boots, it's able to defragment files that are normally in use, which means it does a far more thorough job.
Particularly welcome is the program's ability to work with system data like the Master File Table (MFT). This index holds details of all the files on your hard drive (assuming it's formatted to use NTFS), and it can become fragmented, reducing system performance. Windows own defrag tool ignores the MFT, but Paragon Total Defrag 2010 can optimize it to ensure your hard drive is running at its best possible speed.
