There are many reasons why PCs seem to slow down over time, but file fragmentation bears more responsibility than most. And there's no way to avoid it, either. As files grow, some will inevitably become spread around your hard drive, some clusters over here, some over there, increasing the time it takes to reload the file later.

You could try cleaning up the drive with Windows own defragger, of course, if you've got a few hours to spare, and you don't want to use the PC while it's running. But we think you might prefer O&O Defrag Professional instead: it's a much more professional solution.

There's a much more in-depth analysis of your drive, for instance. You get a sortable list of every fragmented file, all the currently locked files (invaluable in finding out what to close before running a defrag), and statistics on disk structures like the Master File Table (if your drive uses NTFS).

The program comes with five different defrag methods, too, ensuring files will be rearranged in the way that best suits your needs. These include Space (fast but no reorganisation of the volume), and Stealth (makes minimal requirements of memory or free disk space). There are also a range of Complete methods that defrag files, consolidate free disk space, and reorganise files, sorting them by access date, modification date or name.

Defrag Professional can also run at boot time, allowing it to defragment the paging file, Registry, and other files that are normally locked. Add a scheduler, and the ability to run whenever your files reach a specified fragmentation threshold, and you've got the ideal utility for keeping your hard drive running at peak performance.


The latest version of Defrag adds all kinds of useful new features, like improved Windows integration (defrag your drives directly from Explorer), Screen Saver Mode (defrag only when the screen saver is activated), and special support for notebooks (avoiding draining the battery by defragging only when it's plugged into the mains).

As a registered user of version 4 you can upgrade for only £19.99, too, saving £10 on the usual price for a new user. Find out more at www.oo-software.com/en/special/defrag4/
