IObit Smart Defrag Review

IObit Smart Defrag is an outstanding disk defragmentation and optimization solution with numerous advanced features – file placement optimization, boot up speed enhancements and game optimization are just a few.

This defragmenter provides an ultra-fast, stable, and intelligent defrag engine. Additionally, it includes features for analyzing disk health monitoring usage as well.


IObit Smart Defrag is one of the premier third-party defragmenters for Windows, designed to optimize performance across various tasks like browsing, streaming and gaming. Compatible with all versions of OS, this tool can improve browsing, streaming and gaming speeds as well as speed up system startup times with Boot Time Defrag for faster system startup times and Game Defrag that allows gamers to optimize game play for improved experience.

Once you launch the program, all your disks and Metro apps are displayed on the main screen with their current statuses and results of last defragmentation. Each can be clicked for more details such as their free/total size ratios, defragmentation method used and start/finish times of their defragmentation session. Furthermore, when viewing one drive’s report from this list you will also see its pie chart, list of defragmented files/directories/file fragments etc.

With these buttons on the right side, you can choose among three defragmentation methods. Fast Defrag (which may be quick but doesn’t fully optimize disks), Defrag & Optimize (more comprehensive and takes more time) and Auto Defrag can all defrag disks when your computer is idle but this may hinder system performance.

The Settings panel in the primary panel allows you to set a schedule for any of the three defragmentation methods available to you, boot time defrag, specify which drives should be defragmented, as well as whether or not to run defragmentation while your computer is connected or when switching over to battery power. You may also choose whether defragmentation should stop when your system starts operating on battery power instead.

Noteworthy during installation is that additional programs from IObit and its partners might appear. If you don’t wish to install them, click “Hide Text Link at Top” and hide them out of sight; otherwise just continue through with setup as normal and everything should work perfectly fine.
