Difference between Mustang's plugin and Acronis BartPE directory

Another silly question from me, but in creating a BartPE bootable CD I started to wonder what the difference was between the BartPE directory that is found in my Acronis installation (path is C:\Program Files\Acronis\TrueImageHome\BartPE) and Mustang's plugin file that I got from Mudcrab's site here: http://www.purviancecs.com/acronisplugins.htm

Thanks!

 

Mustang's plugin allows Image Mounting which you cannot do with the Acronis supplied plugin. There could be other differences but that is the main one.

 

Okay, that's good to know. So long as there are in fact differences between the two, the I feel better using Mustang's plugin as opposed to the Acronis-provided plugin. Thanks!
