The default disk defragmenter built into the Windows operating system is pretty good, but if "pretty good" won't cut it and you want something that is properly good, then you need to get Piriform's Defraggler. It is a great replacement for the Windows disk defragmenter and an exceptional defragging program overall. You can use it to defrag hard drives, folders, and files. From Defraggler's interface, you can analyze any drive you want and you can manually initiate a Quick or a Standard Defrag job. The Quick Defrag completes faster, but the Standard Defrag job properly addresses fragmentation issues. If you don't want to manually initiate a defrag job, you can schedule it to run automatically. And if you can't wait around the PC to wait for the defrag job to complete, you can set it so Defraggler will shut down your PC when it's done. Besides defragging drives, Defraggler can also defrag folders, files, and free space. Other defragging programs are limited to drives. Defraggler is not!
