Hard drive defragmentation is one of the various disk maintenance tasks that need to be performed regularly to guarantee a fast and safe access to your data. IObit offers you a comprehensive and flexible free tool with all the features you need to perform customized defragmentation processes on all your internal and external storage devices, including USB memories and SSD disks.

Many Windows users may wonder why they should install yet another defragmentation tool when their OS already includes Disk Defragmenter. Actually, if all you ask from a defragmentation utility is to have all your fragmented data nicely re-allocated in the right place and in the right order, this Windows tool will do the trick. However, if you’re looking for a defragmentation tool that knows which files should be placed first based on how frequently you use them, that allows you to defragment specific files and folders only, that defragments your disks on startup if you wish, that consolidates free space, and that is capable of defragging boot files safely, then you need Smart Defrag.

Despite its highly attractive interface, Smart Defrag is much more than just a pretty face – it is a comprehensive defragmentation tool with all the features Disk Defragmenter never had and probably never will. This free utility can analyze all your hard drives (or selected units only) and defragment them in one single operation. It does not matter if they are standard or SSD drives, if they are internal or external, or if they are large or small – Smart Defrag will determine which defragmentation method is best for your drives and the data stored in them, and will perform it in the background without interfering with your work. It will take care of large files, consolidate any free space left, and prioritize your files for long-lasting data contiguity.

You can schedule the program’s defragmentation tasks according to your preferences and to the last detail. Smart Defrag can defragment page files, hibernation files, MFT, and system files before system startup to boost your computer’s performance every time you use it. It can also wipe all junk files present on your disks before defragmenting them, and trim your SSD to get rid of no-longer-used data. Besides, the program comes with game optimization routines that will optimize the games on your system to make them run more smoothly and efficiently.

Smart Defrag is free, easy to navigate, and highly efficient. It requires very little memory, works when your system is idle, and can be easily customized to adjust to your schedule. Not all defragmentation tools are the same, and not all of them are capable of providing you with all the features present in this IObit’s defragmentation tool.
