Recommendations for your first defragmentation

The first defragmentation usually requires the most time because O&O Defrag has to check your entire system and move all files into their optimal position. This is especially the case with systems that have been in use for a long time and have rarely or never been defragmented.

The COMPLETE methods in particular are very time-consuming because the entire file structure needs to be 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!

Defragment Single Drives

  1. Select the drive you wish to defragment from the drive list.
  2. Clicking the Start button in the Ribbon Bar will start defragmentation using the OPTIMIZE default method. If you want to change this method, open the Start button's lower menu and select the Method you desire.
  3. Depending on the size of your database, defragmentation can take up to several hours. You can see the defragmentation in progress on the drive symbol and the status display.
  4. Once defragmentation is completed, you can have a detailed status report displayed as an HTML document in your web browser.

Note: You can defragment several drives simultaneously by pressing the Ctrl key and selecting the drives you want to have included.

Defragment an entire computer

  1. To defragment your entire computer, select all the drives in the drive list. A multiple selection can be done by pressing Ctrl.
  2. If you click the Start button in the Ribbon bar, defragmentation with the OPTIMIZE default method will begin. If you want to change this method, first open the Start button's lower menu and select the Method you desire.
  3. Depending on the size of your database, defragmentation can take up to several hours. You can see the defragmentation in progress on the drive symbol and the status display.
  4. Once defragmentation is completed, you can have a detailed status report displayed as an HTML document in your web browser.

Defragmenting individual files and folder

You can also defragment individual files and folders. Just right-click the folder or file you want and select Defragment. O&O Defrag will be opened and the defragmentation begins. Defragmentation of smaller amounts of data is often completed within just a few seconds.
