O&O Defrag 15 Professional Edition is a comprehensive and highly configurable tool for optimising the layout of files on your hard drive.
You could simply install the program, and forget it. O&O Defrag will automatically reorganise your files to deliver the best hard drive performance, and then run in the background, detecting new fragmented files and defragging them as soon as possible, preventing any further degradation of your PCs speed. (And no, that shouldn't interfere with other programs - in our tests O&O Defrag proved very light on system resources.)
If you like to take a more hands-on approach, though, it's also possible to create your own custom hard drive layout rules. Move unwanted files and file types over here... High priority documents over there... Leave particular system files in that corner... It takes some thought, but if you're an experienced Windows user then there's no reason why you can't make careful use of O&O Defrag 15 Professional Edition to squeeze even more speed out of your system.
And however you intend to use the program, you'll appreciate design details like the clear, easy-to-use interface; the excellent defrag scheduler; the SSD support, using regularly scheduled TRIM commands to improve write speeds; the Explorer integration (defrag any file or folder from a right-click option); the notebook support (defrags are optionally disabled when you're running on battery power); and the ability to run defrags before Windows loads, allowing the program to defragment system files that would otherwise be locked.
If you've tried the program previously and found it a little slow on occasion, the good news is that version 15 sees the various algorithms tweaked to improve defragging performance by up to 40%.
New "before" and "after" images give a visual impression of how your system has been optimised by the defrag process.
A new History tab plots your drive's file fragmentation over time, so you can see how Defrag Professional is improving the situation.
And the program can now update itself automatically. No need to register or manually download or run files, Defrag Professional handles everything itself so you can be sure you'll always have the very latest version.
