O&O Defrag 15 Professional

Maximise your PC performance

O&O Defrag 15 Professional

By defragmenting your PC's hard disk you can drastically increase speed and performance, plus work more efficiently.

Why do I need O&O Defrag 15 Professional?

An increasingly fragmented hard disk can affect the performance of your computer, making it slow and sluggish. Windows disperses single file fragments all over the hard disk, which increases the time for it to access and load files, therefore slowing down your entire system. Defragmentation with O&O Defrag gives you faster system starts, speeds up programs, and prevents new fragmentation from even occurring.

Main functions of O&O Defrag 15 Professional:

  • Defragmentation of your PC at the push of a button
  • Performance increases of up to 100%
  • Prevents new fragmentation from occurring
  • Organises related file fragments on your hard drive
  • Faster system and program starts
  • Extends the life of your hardware
  • Automatic defragmentation runs in the background

And many more great features.
