Smart Defrag Portable is a free, lightweight, and stable disk defragmentation program designed to optimize hard drive performance. Based on IObit's latest disk defrag engine and "Boot Time Disk Defrag" technology, Smart Defrag Portable not only defragments your files as any other disk defragmenter can, but it also intelligently streamlines your files based on their usage frequency, accelerating disk speed for faster data access. 

It uses the unique Deep Analyze technique to remove trash files before defragmentation, saving you extra disk space. As the first disk defragmenter to completely support Windows 8/8.1/10 Metro Apps, it works quickly, automatically, and quietly in the background, making it ideal for huge hard drives.

Features and Highlights

Increased File Access Speed 
Disk fragmentation is typically the leading cause of poor and unsteady computer performance. The utility accelerates your hard drive for faster data access and superior disk performance by employing multi-threading defragmentation technology on hard drives and SSDs, as well as consolidating free space and defragmenting huge files. You'll be able to launch games faster, copy files in half the time, and so on. 

Up to 100% faster PC startup
Specific boot files on the system disk cannot be properly transferred while Windows is active, resulting in progressively slower system restart. The tool's Boot-time Defrag option will simply perform this for you, allowing you to safely defrag data on your hard drive. Furthermore, utilizing an IObit-exclusive function, you may personalize the defragmentation of specific folders during the system boost. Following that, you will be able to enjoy faster PC startup and top running speed on your PC while maintaining the highest level of stability. 

Safe & Automatic Disk Defragmentation 
Smart Defrag for Desktop not only performs disk defragmentation like any other tool, but it also improves it by automatically simplifying your files based on their usage frequency. IObit's latest disk defrag engine is just as safe for your files as Windows. And all you have to do is install and forget it. It will work automatically and without losing any data. 

Faster PC & Access Speed 
Disk fragmentation is the primary cause of sluggish computers. With an upgraded multi-threading defrag engine and defrag speed, it offers a better option for faster data access and exceptional disk performance. You'll be able to launch games faster, copy files in half the time, and so on. 

Faster System Boot-Time 
It takes longer for your computer to boot up and begin to function as it ages. This difficulty is easily solved with the app. Configuring the Boot Time Defrag function allows files on the HDD that cannot be moved while the system is running to be swiftly defragmented for a speedier startup. 

Enhanced game performance
