Auto Defrag

When you’ll click on this option, the software will automatically start the defragmentation. You can also call it Quick Defragmentation. But it is only for Pro users, so in order to activate this feature, you have to purchase its premium version.

Boot Time Defrag

When you defrag something through Smart Defrag, it defrags only those data which do not run during the defragment. But there are lots of files which keep on running at the back end of the PC. 

These files cannot be defragged when the computer is in running condition. These can defrag only during boot time. That’s why Boot Time Defrag feature works during booting of computer.

When you hover the cursor on the blue color Smart Defrag button located just below the drives name, all 6 options display to defrag the drive.
