Installation and System Requirements - O&O Software

Technical Information
Using the Command Line Version
You can also control the defragmentation by means of the command line version of
O&O Defrag. In this way, you can also integrate O&O Defrag into scripts that you run at
startup or login.
When you start the program from the command line, the main interface window will not appear.
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 processes later by using the STOP command,
Tipp:
If you start O&O Defrag from the command line, you can also start the main user inter
face later. This will show you the status as usual without interrupting or stopping the
running processes.
