Features and Highlights

Increased file access speed 
Disk fragmentation is often the root cause of slow and unsteady computer performance. The utility accelerates your hard drive for faster data access and superior disk performance by leveraging multi-threading defragmentation on hard drives and SSDs, as well as consolidating free space and defragging huge files. Then you can enjoy faster game launch speeds, file copying in half the time, and so on. 

Up to 100% faster computer startup
Specific boot files on the system disk cannot be properly transferred while Windows is active, resulting in an increasingly delayed system restart. The tool's Boot-time Defrag option will effortlessly complete this task for you, allowing you to safely defrag data on your hard drive. Furthermore, it uses a technology exclusive to IObit to allow you to defrag specific files during system boost. After that, you can experience a faster PC startup and maximum running speed on your PC while maintaining the highest level of stability.
