You can also control the defragmentation by means of the command line version of O&O Defrag. In this way, you can integrate O&O Defrag into scripts that can be run at startup or login.

The graphical user interface of O&O Defrag will not be shown during a start from the command line. A mini O&O Defrag icon will appear in the task tray, and you can follow the progress of the actions in your DOS prompt.

O&O Defrag runs independently of the main user interface and the DOS prompt in the background. If you close the DOS prompt or cancel the command line tool with Ctrl+Break/Ctrl+C, you can choose whether to end the program or have it continue in the background. You can also cancel the started activity later with the help of the STOP command or by using the user interface.

Tip: If you start O&O Defrag from the command line, you can also start the main user interface later. This will show you the status as usual without interrupting or stopping the running processes.
