Smart Defrag

If you are looking for Smart Defrag, you have come to the right place. We explain what Smart Defrag is and point you to the official download.

What is Smart Defrag?

Smart Defrag is a free tool from IOBit that enables a faster (and smarter, as is evident from the name) defragmentation of the user’s hard disk to enable a smoother PC experience, and iron out inconsistencies in the computer’s performance.

Windows has a built-in defragmentation tool, but Smart Defrag works faster and more efficiently than this integrated tool, as it performs the same function at about a fraction of the time than Windows does, and is safer; usually, when Windows uses a defrag function, the system may lock up, or the read/write process may not complete fully when the user does something (especially ones that are disk-intensive) when a defrag is happening.

Smart Defrag bypasses all these problems with its exclusive technologies, which makes defragmenting – especially a pain for huge hard disks, like 1 TB and up – still a breeze with its patented Boot Time Defrag technology. This enables the application to defragment the files on your hard disk during the boot-up process, allowing you to enjoy the maximum benefits of your computer when you need it. It also features a background defrag system that continually defragments your PC, plus a disk optimization technology that not only defragments your disk, but also cleans and streamlines it.
