Smart Defrag does not provide a backup or restore point feature baked into the utility. We always recommend backing up your system before performing any software or driver updates. Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP are all supported, including 32-bit and 64-bit versions. Smart Defrag's scheduler function allows defrags to be set up regularly, or even set to defrag when your PC is plugged into a power source, ot when CPU usage is below a certain threshold. One of the best features is Automatic Disk Defrag option, a which reserves defrag time for when your computer is idle. The result is up to a 100% improvement in PC startup time. In order to speed up boot time, Smart Defrag safely moves system boot files which typically cannot be moved while Windows is running. It consolidates free space using an efficient multi-threaded defragmentation technology which results in improved file copy speed and faster game launching time.

Smart Defrag is an ultra-fast, stable and reliable Disk Defragmenter utility with over 7 million users.
