You can start PSPad by double-clicking on the PSPad.exe file in Windows Explorer, by double-clicking on any file that is associated with PSPad (see System integration) or by dragging and dropping a file on to either the PSPad.exe file or a shortcut to it.
The syntax to start PSPad from the command line is:
PSPad "drive:\path\filename" [/switch]
Note: The PSPad directory must be in your $PATH environment variable for this to work. If it isn't then you must enter the full path to the PSPad.exe file.
If the filename passed to PSPad is a PSPad project file (see Working With Projects) then PSPad will open and load the project.
For switch values see Command line parameters.
