The /e parameter allows you to specify the full path to an exe (exepath) file that you want to start. The exepath may use any of the following substitution strings as shortcuts to commonly used directories: {windir}, {sysdir}, {startdir} and {desktop}.
The /a parameter allows you to specify arguements that will be passed to the executable file that you are launching. The arguments may also use the same substitution as in the exepath.
The /w and /h parameters allow to specify the final width and height of the application window. These parameters must be used together.
The /x and /y parameters allow to specify the final position of the application window. These parameters must be used together and will override the /c option.
The /c parameter tells ncstart to center the application window on the desktop.
The /t parameter tells ncstart to make the application window a topmost window.
The /m parameter tells ncstart to maximize the application window at startup.
The /b parameter tells ncstart to make the application window borderless
