The user interface is rather simple, yet it offers a lot. It is also easy to navigate, so novice users will not have a hard time trying to use the program. The program window is divided in two – in the upper part you see all drives connected to your computer; the bottom part shows the current state of your drives, a few options for automatic defragmentation and boot time defragmentation, a report section and an action center that acts as a hub for additional software.

Of course there's a Settings section too, where you can change the program settings to fit your needs. Once done with everything, just click the Defrag or Analyze buttons and start the program. A major flaw, though, is that you can't expand the drives section, no matter how you try and this is something that limits you to working with four drives at most.

Basic Operations

Working with Smart Defrag 4.0 is a breeze, just open the program, analyze your drives and click on the Defrag button. The software will then start working and after some time (depending on the number, size and defragmentation state of your drives), you will get a noticeably faster machine, especially when working with your system drives. Smart Defrag also supports file and folder defragmentation – a function that will also ease working with files and folders and especially those that are large in size.


Probably some of you will ask, why I need this utility, when Windows OS already have one. Yeah, you are ready, but not quite. Smart Defrag comes with a whole bunch of features, which provide you with better control over your hard driver. That's not all. Using it, you will achieve better defragmenting results as well.
