Smart Defrag optimizes your Windows PC to boost its performance for gaming, streaming, browsing, and other desktop activities. It’s one of the best Windows 10 defrag tools ever made.

Defragmentation is an operation that reduces file fragmentation by rearranging pieces of data from storage devices to make the small contiguous areas longer. To put it in simple terms, it improves the performance of your computer by speeding up file-related processes, like opening files.

Having a defragging utility on standby is as necessary as having a disk cleaner. We’re talking about small but essential Windows tools that can do wonders for your PC, especially if you have an HDD instead of an SSD.

One of the best defragging tools in the business is Smart Defrag. Created by the same team behind Advanced System Care, IObit Uninstaller, and Driver Booster, Smart Defrag is a Windows program that promises to get your PC in shape by reducing the degree of file fragmentation.

Our Review

Intuitive interface and controls
Multiple defrag modes
Free version available
The pro features can't be tested for free

Smart Defrag is incredibly easy to use, thanks to its intuitive interface and controls. It has a greater appeal than the Windows integrated tool for drive defragmentation and optimization. What’s more, Smart Defrag has special features reserved for disk defragging, game optimization, and boot time defragging.

Check out our Smart Defrag review below but not before taking a look at the limitations, system requirements, setup procedure, interface, feature set, and how-to-use steps.

Smart Defrag free version

Most users will be happy to know there’s a free version of Smart Defrag available. It gives you the possibility to use all critical features for free. However, some options are locked. For instance, you can’t use the Auto Defrag tool or defragment registry and custom files when using Boot Time Defrag.

To sidestep these restrictions and use the complete package, you have to buy Smart Defrag Pro. Make sure to keep an eye out for IObit deals if you want to get a reasonable price for this application.

Smart Defrag system requirements

Before downloading and setting up Smart Defrag on your PC, check if your system meets these conditions:

  • Processor: 1 GHz or newer CPU
  • Disk space: around 200 Mb
  • OS: Windows 10, 8.1, 8, 7, Vista, XP (either 32-bit or 64-bit)
  • Other: administrative rights

How to install Smart Defrag

When setting up Smart Defrag on your computer, you can review the license agreement, choose a setup older, and create a desktop icon. The tool also offers to download and install an additional software product, which it doesn’t need for disk defragmentation. As such, you can decline the offer if you’re not interested. Smart Defrag gets launched as soon as the setup is over.

Smart Defrag interface

As for the graphical interface, the defragging utility is modern and sophisticated. The main window has a dark theme and displays large buttons to help you carry out tasks right away.

Four tabs provide you access to all essential features: Disk Defrag, Boot Time Defrag, Game Optimize, and Action Center. To configure general settings, you have to open the ≡ menu. For example, you can adjust the main window’s transparency.

How to use Smart Defrag

To quickly defrag your disk with Smart Defrag, here’s what you need to do:

  • Select your disk drive from the main window and pick a defrag mode
  • If you’re not sure about what to choose, go with Smart Optimize
  • Wait until the defragging job finishes
  • If the task takes too long and you need to step out, enable Shut down after optimization
  • Click View Report to open an HTML report in your default web browser and get more details about the total defragged files

A feature-rich and easy-to-use disk defragging tool

Taking everything into consideration, Smart Defrag proves to be a dependable disk defragging tool for Windows users. It comes bundled with many defragmentation modes, which it carefully explains in the help manual. Surprisingly, it doesn’t take a toll on the computer’s performance.

Even so, you shouldn’t do anything on your PC while Smart Defrag is busy with a task since you might alter results. Smart Defrag supports multiple UI languages. Thanks to its clear-cut interface and options, anyone can use it to optimize their PC performance by regularly running disk defragging tasks.
