FREE Defragment Tool Automatically Speeds up Computer in Minutes.

Smart DefragOverview

Smart Defrag is a reliable, stable, yet easy-to-use disk optimizer designed for peak hard drive performance. Unlike other disk optimization tools which only provide traditional defragmentation, Smart Defrag also intelligently streamlines your files based on using frequency to accelerate disk data access and lengthen disk lifetime no matter whether it is a HDD or a SSD.

What makes Smart Defrag special and attractive when compared with other disk optimizers?

Defrag HDD Smartly
The smart IObit disk defrag engine makes optimizing HDD easy and effective, greatly improving HDD's reading/writing speed, access speed, and performance.

Trim SSD Intelligently
While SSD sweeps the computer world, it is also necessary to care for SSD. Smart Defrag introduces the world-leading technology to trim SSD and prolong its lifetime.

Optimize Disk Automatically
Auto Defrag and Scheduled Defrag ensure your disks are always optimized to their top performance. You are totally free from starting an optimization manually.

Optimize Disk Thoroughly
Some fragments can't be defragmented while the PC is running. Boot Time Defrag can defrag the Windows registry and files in every corner of the disk at system startup to release more occupied RAM and ensure system stability.

Provide Better Gaming
Besides considering common computer users, Smart Defrag also considers gamers. Game Optimize can bring an ultra-smooth gaming experience.

In summary, Smart Defrag is a must-have disk optimization tool for quicker data access, faster file processing, and smoother gaming on Windows.
