O&O Defrag

Paid option

This function requires O&O Syspectr Premium or a higher edition. Compare the editions

O&O Defrag defragments your drives and so speeds up access to them. When writing, the file system often splits files into several pieces and scatters them across free areas of the drive. To read such a file, all its pieces must be found and put together again, which takes time – on a hard disk, the read/write head has to move physically. Once the files are stored in one piece and in order, access to them becomes much faster. On hard disks, this also reduces the wear on the mechanics.

Installation​

To use O&O Defrag, its current version must be installed on the computer. If it is not, O&O Syspectr installs it fully automatically. Confirm the installation and wait a moment until it is complete. Then you see an overview of your drives and can start the actions you want.

Actions​

Analysis​

The analysis examines the partitions of the computer and shows how fragmented they are and how the files are distributed on each partition. Red blocks stand for fragmented files, blue blocks for defragmented files.

Defragment​

When you start the defragmentation of a partition, O&O Syspectr shows its progress at regular intervals.

Stop​

Stop ends a running analysis or defragmentation within a few seconds.

Offline functionality​

You can query and control O&O Defrag even when the computer is not reachable, that is, switched off or not connected to the Internet. If you start an analysis or defragmentation while the computer is offline, O&O Syspectr shows a notice; you can withdraw the action at any time with Cancel. As soon as the computer is reachable again, the action is carried out automatically. You can look at the result later at any time, even if the computer is offline again by then.

Tasks​

Partitions​

Select the partitions for which you want to create a defragmentation task.

Execution​

Specify whether the task runs once on a certain date or weekly on one or more days of the week. You can also specify that the task runs at the next opportunity if it could not start at the scheduled time (for example, because the computer was switched off).

Settings​

Automatic defragmentation​

  • Automatic defragmentation in the background – O&O Defrag chooses the best methods and times for defragmenting itself, based on system parameters it determines regularly. The O&O ActivityMonitor regularly measures the load of the system and adjusts the resources O&O Defrag uses to the current state of the computer. This way you can continue working undisturbed while O&O Defrag runs in the background.
  • Optimize when the user is away (when the screensaver is active) – O&O Defrag starts whenever the computer is not being used and the screensaver is active.

Additional automatic optimizations​

  • Optimize SSDs regularly using TRIM – O&O Defrag optimizes solid-state drives (SSDs) of any manufacturer. Write access to the SSD becomes measurably faster, and premature wear is avoided.
  • Regularly delete free space on hard disks – Deleted files can be restored with very simple means. To prevent this, O&O Defrag can wipe the free space in addition to defragmenting, so that deleted data can no longer be recovered.
  • Regular Thin Provisioning optimization – On virtual hard disks, this releases unused space again.
