Command-line Parameters

CCleaner only supports a few command-line parameters.

CCleaner Setup has 3 command-line parameters:

/S - This will install CCleaner with the default options. You will not get a setup screen!

/D - This will change the default install directory of CCleaner. Example: /D=C:\CCleaner

Best used like ccsetupXXX.exe /S /D=C:\CCleaner

/L= - This will install CCleaner with the language file you choose.

Example: /L=1033

CCleaner has 3 command-line parameters:

/AUTO - Runs the cleaner upon loading and then closes the application.

The CCleaner /AUTO parameter can be used in and with:

• Batch files (.bat).
• Shortcuts/links such as; making one on the desktop named CCleaner (Auto).
• Via the Windows Task Scheduler.
• From within CCleaner itself which will allow it to run at every system startup and/or logon.

This is the parameter to use in shortcuts, batch files, or in Task Scheduler (including the quotes) (three examples included):

• "C:\Program Files\CCleaner\ccleaner.exe" /AUTO
• "%ProgramFiles%\CCleaner\ccleaner.exe" /AUTO
• "C:\Progra~1\CCleaner\ccleaner.exe" /AUTO

To make it run at every system startup do the following:

1. Run CCleaner.
2. Click Options->Settings, then tick:
   Run CCleaner when the computer starts
3. Done, you can now close CCleaner.
   Note: This will only clean the User Profile it was enabled on.

To automatically clean All User Profiles on Windows XP (when each individual user logs onto their user profile):

1. Navigate to:
   C:\Documents and Settings\All Users\Start Menu\Programs\Startup
2. Right click and create a New Shortcut and input one of the three example parameters listed above.

/DEBUG - Runs the program in debug mode, only recommended for advanced users.

The command-line parameters can be useful if you don't want to hit the Close/Exit every time, or if you are having a problem, and need to find out what is crashing CCleaner.

/SHUTDOWN - This will shutdown your PC after cleaning. Must be used with /AUTO.

The command-line parameters can be useful if you don't want to hit the Close/Exit every time, or if you are having a problem, and need to find out what is crashing CCleaner.

To do this, Right Click on the CCleaner shortcut, and then click on Properties. In Target, you should see something like this: "C:\Program Files\CCleaner\ccleaner.exe". Just add the command-line parameter at the end, it should look something like this:
"C:\Program Files\CCleaner\ccleaner.exe" /AUTO /SHUTDOWN
