How Disk Defrag Works

Ultra-Fast Engine

One of the fastest defraggers in the world, Disk Defrag often takes less than 10 minutes to defragment an average-size hard drive.

Consolidates Free Space

Merges scattered pieces of free space into a contiguous block, preventing fragmentation of newly created files.

Lists Fragmented Files

You can see which files are the most fragmented, as well as the location of each fragment on the disk map.

Defrags Single File
or Folder

Can save you time by defragmenting only the files or folders you want instead of the entire hard drive.

Works the Way You Want

You can use the default settings for convenient one-click defrags or customize program operation and appearance to fit your needs.

Industry-Acknowledged Quality

Exclusive Auslogics technology is proven safe and effective in multiple tests, used by PC manufacturers and recommended by experts.

Industry Acclaimed

Recognized by leading IT magazines and online resources

"This system optimization tool suite takes an everything-plus-the-kitchen-approach to cleaning, optimizing, and potentially speeding up your PC. Auslogics BoostSpeed includes modules and wizards for just about any kind of tweak or optimization you can imagine..." Learn more "It is almost impossible to manually remove junk files and registry errors, but there are some handy tools out there that can do it for you. One of them is Aulsogics BoostSpeed. With this program you can maintain your PC at top speed with just a click of a button once a week." "To prevent system slowdown from happening, regular defragmentation of your disk and registry is recommended. You can defragment your disk with the built-in tool from Microsoft, however we recommend using the faster and more avdnaced version in Auslogics BoostSpeed." "Removing junk files manually can be a tedious process, but a nifty software from down under called Auslogics BoostSpeed can do it for you automatically. It will remove junk files and optimize the one-sit-fit-all Windows settings to your hardware. For additional speed boost it will fix registry errors and optimize your Internet settings." "Of all the optimisation tools I've tested over the past few years, I'm happy to write that Auslogics BoostSpeed is one of the most comprehensive and user friendly, ... I couldn't recommend it highly enough." "Speed up your slow computer and Internet with this Editor's Choice software." Learn more "BoostSpeed is an effective all-encompassing utility suite, combining some of Auslogics' popular freeware titles with services that they don't offer elsewhere... No doubt, BoostSpeed gives you your money's worth." Learn more "Another source of identity theft are files with sensitive information. Simply deleting them doesn't make them go for good. It's quite easy to "undelete" them and use in ways you probably will not be happy about. But if you delete a file, or a folder with Auslogics' File Shredder, you can be sure that they will be impossible to recover." "This meticulously written application is an ideal solution for anyone who wants to boost their computer for peak performance without costly hardware upgrades. BoostSpeed gives you a combination of 15 precision-engineered modules to clean-up and defragment your computer disks, fix registry errors and speed up internet connection." "Think of the best PC speedup suite you've tried. And then add more. More tools. More features. More depth, more extras, and more thought behind everything. That'll give you some idea of what to expect from this excellent program..." Learn more "All in one performance tool for your PC that is very easy to use." Learn more "Auslogics BoostSpeed will give you the ideal solution to keep your computer running smooth and fast." Learn more "Auslogics BoostSpeed can protect you from identity theft. Being a useful computer optimization tool, it also includes a number of very useful privacy and security applications. It offers advanced protection where anti-virus software can't help." "You can clean up, optimize and defragment your PC using Auslogics's OneButton Checkup. Tests showed an impressive performance improvement on a 4-year old laptop and its optimization techniques should work for a much newer computer, too." "Auslogics Boost Speed is a worthy alternative to constantly having to upgrade your computer. Even if your computer is relatively new, the program will keep it running fast and error-free for a long time." Learn more "This is a smart little program that novice users will find handy, and it does a good job of explaining itself and the various tweaks it offers."

Hi there, i would just like to say i have had the Auslogics Disk Defrag programme installed on my computer for maybe 1 hour and it is fantastic ! I remember about 10 years ago i used a Defrag programme and since then i have changed so many computers, upgraded, built them myself that i just didnt bother with Defragging again, but ive recently researched some programmes and thought it may be good for a hard disk to be Defragged. What i love about your programme is, when you select the drive and you right click on the mouse, it is very easy to use and the options are excellent i.e Analyze, Quick Defrag, check for Drive Errors etc It`s a complete programme that is very simple to use and really seems to care about a customers hard disk just by the fact the programme isnt too basic and thrown together quickly just to look good and doesnt really do a good job. In my opinion, its excellent because the 5 drives i have in my computer have not had the attention they really need for a long time, and i can do all this just by selecting the drive and right clicking the mouse and having these great options. AND....the programme is free :)
