Defragment your HDDs and USB devices and trim SSD drives and Windows apps.

Unless regularly addressed, disk fragmentation may easily become one of the factors that make your PC or laptop seem to drag on lately.

Fragmented files and frequently-accessed files located in the wrong end of your disk are harder to read and load, and those are but two of the tasks that Smart Defrag has been designed to tackle. Suitable for both HDDs and SSDs, internal and external, this tool can keep your disks in top form in no time.

The program’s interface follows the elegant dark-colored design common to all IObit tools. Defragmentation utilities are especially attractive in their visuals, as they usually make use of color codes to define the state of each cluster during the defragmentation process. You can swap between the default color map and an alternate and more accessible version, designed for those users with difficulties in identifying certain colors.

This comprehensive utility performs all the basic defragmentation tasks for free and adds a few high-level routines (such as registry files and custom files defragmentation) to those users willing to upgrade to the Pro version. Actually, if you only need to defragment your hard drives and trim your solid-state drive regularly to keep your system’s performance level in top condition, the free version that you can download directly from the official site is all you need.

Smart Defrag keeps you informed at all times of the fragmentation rate of your disks, the fragmented files in it, and the files defragmented in the process. It includes a special routine (included in the standard process) that deals with large files specifically, and that you can launch separately if you wish. You can also check your disks’ health at any time, with real-time information about the disk’s temperature, usage, read and write speeds, response times, and a more detailed self-monitoring analysis report. There are also special optimizations tasks for gamers, allowing them to select a game and have all its files neatly defragmented for quicker file access.

Smart Defrag is getting smarter and smarter on each new iteration. This is an excellent tool to forget about file allocation problems and slow file access speeds, as long as you use this tool regularly or whenever a high defragmentation rate makes it advisable.

If you have the free edition, this is a downgrade of Free SmartDefrag, to keep full option you need tu purchase, otherwise is better to go back to the old 4.0 and you have about everything.

This is such a useful tool, I am surprised it's free. Like Lit, I recommend it.

Smart Defrag 4 - I miss the Automatic Defrag screen that showed CPU usage, Disk Drive Usage & Defrag History graphs. Was useful - sorry it's gone in Version 4.
