| CCleaner.exe /EXPORT | CCleaner exports the cleaning rules to the INI files. Three INI files will be created in the CCleaner's installation folder - winapp.ini, winreg.ini and winsys.ini. They contain cleaning rules for the Application section, Registry Cleaner and the Windows section respectively. |
| CCleaner.exe /DELETE 'path_to_file(s)' /METHOD '0-3' | CCleaner silently performs secure deletion for folders/files specified. You can specify multiple files/folders separating them with the '|' character. Example: CCleaner.exe /delete 'D:TempSDelete*.*|D:TempSDelete*.log|D:TempSDelete*.txt|D:TempSDeletetest.bmp' The Method parameter defines the secure deletion type: 0 - 1 Pass Note: You cannot use /METHOD by itself.
