Hi Chip
It might be a mac thing :) I use windows and its about 80mb
I just dragged a copy of my entire moi3d folder from the program files into my dropbox folder.
I have the ini, my startup template, and V2 and 3 licience in the moi folder (as I use it as my USB portable version also )
At a meeting today with my laptop dropbox synced itself and I could run Moi straight from it .
When I saved a new object with Max's custom UI it updated the drop box and was available in my workstation back at work.

Works brilliantly especially for designs I did at the meeting that I can access from dropbox without having to copy them in.
