Smart Defrag 4 can work automatically in the background on PC, keeping hard disk running at its top speed. With Game Defrag, users can also manually add games to the Smart Defrag 4 to be defragged separately from the complete storage drive defrag, for top gaming performance. Smart Defrag 4's updates include a new defrag engine, specialized Game Defrag, a cool new look, and many more language options (35 and counting). Its SSD Trim tool automatically enables system tweaks that typically require experience to apply. Smart Defrag is a well designed, effective and flexible application.IObit Smart Defrag 4 optimizes your PC to take full advantage of SSD performance while defragmenting your hard disks. Smart Defrag can be set to defrag only when a computer is plugged in (not running on battery power), and also to pause if CPU usage reaches a predetermined percentage. Smart Defrag's schedule tab allows defrags to be set up regularly, and in Options there are some very useful settings. You can set this to run every boot-up, or just once every few days. There’s also a Boot Time Defrag, which allows you to defragment files that are dangerous to move while Windows is in use. It's a neat solution, as doing a full defrag can be a lengthy and resource-heavy process. Turning on Automatic Defrag means Smart Defrag will reorganize your drives whenever the system is idle. You can also pause scans or tell Smart Defrag to shut down the computer when it has finished.

It’s also here that you can choose what kind of defrag you want to run – pick between Defrag Only, Defrag and Fast Optimize, or Defrag and Fully Optimize. The first is where you’ll see details of whatever scan is currently running. The application has four main sections: State, Automatic Defrag, Boot Time Defrag and Report.
