Hi,
Like I said, I don't have a Snap but if I'd venture a guess something along the lines of:
Code:
-TPSNAP -P$target-device$ -F$hex-filename$ -E -M -OL
Programmer exectuable is ipecmd.exe

In your MPLABX installation path you'll find a subfolder called docs. There you'll find a file, Readme for IPECMD.htm, take a look at that.

/Henrik.
