Use Defraggler to defrag your entire hard drive, or individual files – unique in the industry. This compact and portable Windows application supports NTFS and FAT32 file systems. Most defrag tools only allow you to defrag an entire drive. Defraggler lets you specify one or more files, folders, or the whole drive to defragment. Pick the trouble spots on your hard drive – like your favorite videos, your business software, or your Web browser. Defraggler does exactly what you tell it to.

Defraggler goes one step further and defragments the free space, too. If your free space is fragmented and all chopped up, new files written to that space will end up fragmented right away. Defraggler can defragment free space so new files are automatically all in one place, making your hard drive run faster and Windows work more effectively. Defraggler runs in the background so you can continue to work, play, and have fun. It’s small and uses few system resources, so you won’t experience any slowdowns in the process.
