The best way is to put them in an addition folder "helpers" in your "unofficial" folder.
(<LDRAW Base directory>\Unofficial\Helper).
Then open you MLCad.ini (this is stored in your MLCad folder). Some lines before the very end of this file, you will find a section [SCAN_ORDER]
Just add a line with a new number:
note: X is a placeholder for your number here.
Restart MLCad. Maybe you have to set up your parts tree, that it shows the helper. (I'm not sure about this)
/Max
