Defragmenting your volumes

Select the volume you wish to defragment from the volume list.

Start the defragmentation by clicking on the start button on the taskbar, or choose the desired defragmentation method from the context menu.

Depending on the size of your volume, the defragmentation can take up to a few hours. O&O Defrag will display the estimated time remaining in the volume list. You can follow the defragmentation process via the volume symbol and the progress display.

Whilst O&O Defrag is running, you can carry out your work on the PC undisturbed.

After the defragmentation is finished, you can display the detailed status report as an HTML document in your web browser.

Note: you can defragment several volumes simultaneously. Mark the various volumes by keeping the Ctrl key depressed whilst selecting S.

Tips for your first defragmentation

As a rule, the first defragmentation will take the longest, as O&O Defrag has to perform a complete check on your system and perhaps move fragmented files into an optimum position. Especially with systems that have been in use for a long time and have seldom or never been defragmented, this can take a long time.

The COMPLETE methods in particular are very time-consuming, because the entire file structure is thereby optimized, which involves moving even files that are not fragmented. We therefore recommend an initial defragmentation with the STEALTH or SPACE methods. These methods consolidate your hard disks very quickly and efficiently. Afterwards, you can use the COMPLETE methods for optimum performance or stick to the quicker STEALTH and SPACE methods. Whichever method you choose, your system will be significantly quicker than it was before!
