Defragmenting your hard drive can make a real and significant difference to your PCs performance. So it's a pity that Windows' own defrag tool is slow, short on features and has a poor interface, especially in Vista. Fortunately, there are plenty of alternatives around, and IObit Smart Defrag is one of the best.

The program has a variety of defrag strategies, for instance. You're able to defragment files alone, defrag and compact free hard drive space, or use a "deep optimise" mode to reorganise your hard drive files for the best possible speeds. All work quickly and efficiently.

You're able to launch any of these defrag options on demand, on a schedule, or even in the background after your PC has been idle for a few minutes. We wondered if this meant the program would compromise the performance of other applications, but this really isn't the case. Smart Defrag needs less than 15MB of RAM, doesn't fire up until your system has been idle for 5 minutes, and stops as soon as other applications become active again, so it never got in our way. All you'll notice is an all-round speed boost as Smart Defrag fixes any defrag issues automatically before they become too serious.

Smart Defrag also includes a "Boot Time Defrag" technology which allows you to defrag files during the system boot process - these are files that cannot be defragged or are not safe to move after Windows is running.

Includes a 3-PC, 1-YR license.

Performance Issues?

Most system performance issues are often a result of other software clashing with your brand new software. For instance, security software can clash with a background process, such as a system maintenance tool or defragmentation software. Another cause of system slowdown, is a result of two software applications performing a similar task. As an example, Windows includes a firewall switched on as a default. Your new security suite is likely to include a firewall. You only need one firewall running. In this example, try turning off your system firewall.

Uninstalling Your New Software

Occasionally you may need to either temporarily or permanently remove your new software.

On a Windows computer, go to the Control Panel and choose Programs and Features. Locate the program within the list, then click it to highlight it. Finally, click the Uninstall button at the top of the list and follow the instructions to remove the program from your PC.

On an Apple Mac computer, using Finder, locate the Applications folder. Within the Applications folder, find the name of the application you wish to remove. Simply drag the icon to your Trash icon in your dock. Empty the Trash to remove the files from your computer.

Still Having Problems?

If you cannot solve your system performance issues or are struggling to remove your software, we advise contacting the software manufacturer. If you placed an order, see the section in the order which states Support options. Alternatively, go to the Contact Us page to contact store support directly.
