O&O Defrag 21: Functions

Up to 100% increased PC speed: There is nothing worse than when you want to do something on your PC and your computer is running slow. A disk defragmenter used regularly can speed up a PC of any age and get it working like new again!

Don’t let a slow computer spoil your work or fun! Let O&O Defrag optimize your hard disks and you can experience speed increases of up to 100%! Regular disk defragmentation optimizes your PC performance!

When you defragment, the files that Windows splits up when saving documents across the hard disk are logically put back together again so that files can be quickly recognized and found by the read and write heads inside your hardware. Speed increases of up to 100% are not uncommon, and your hardware suffers much less wear and tear!

If you spend a lot of time on your PC, slow system and program starts or system crashes while playing can be very frustrating. Periodic defragmentation often works wonders in bringing new life to a PC.

O&O DiskStat

O&O DiskStat enables you to analyze used space on your hard disk with the help of Charts (Pie chart or Bar graph). As soon as you start the program, you are presented with a concise overview of your entire hard disk. With the help of O&O DiskStat, you can identify and dispose of superfluous files, saving yourself valuable hard disk space in the process!

O&O DiskCleaner

The brand new in-built O&O DiskCleaner searches for and removes temporary and unnecessary files that are taking up memory and increasing fragmentation. O&O DiskCleaner also increases the security of your data, as private content (e.g. Thumbs.db, copies of documents, drafts of emails, Dumps) will no longer be kept as copies in unnecessary system files.

Benefits of a clearly laid out hard disk

Whenever it saves data, Windows scatters file fragments all over the hard disk and this slows down access times considerably. Defragmentation reverses this by rearranging data and speeding up access times dramatically. This not only saves the user time, it also reduces wear on hard disks and extends their life expectancy. Defragmentation can even make the difference if you lose important data because chances of full recovery are better on a defragmented disk. Why? After defragmentation, it’s easier for data recovery software such as O&O DiskRecovery to restore files when they’re not scattered across multiple areas of a hard disk.

Automatic background defragmentation

Automatic defragmentation can be configured with just three clicks and optimizes your disks behind the scenes with no negative impact on your computer’s performance. You can set O&O Defrag to run defragmentation at a certain level of fragmentation, on particular days of the week, or whenever your screensaver is being used. Defragmentation can be paused and resumed whenever you want because O&O Defrag automatically recognizes where defragmentation was interrupted.

Recommended use

We recommend manual defragmentation for PCs that are being used heavily because only a user can decide when the time is right to give up the performance needed for running defragmentation. On computers using video editing or graphics applications, O&O Defrag can be configured to not start automatic optimization while certain programs are running. The default settings in O&O Defrag are more than adequate for ordinary desktop PCs running mainly internet or office applications. O&O Defrag is also perfect for notebooks. Whenever an external power supply is disconnected, O&O Defrag automatically goes into pause mode to save energy
