Kevin,
You've captured my thoughts.
I know that if I'm at a Mac somewhere, I can go to my on-line Dropbox and DL my encrypted DMG, enter my PW and voilà .
I was just wondering if I'm at a PC somewhere, can I also DL and open the DMG just as I can with a Mac.
From my readings (Google findings), I have concluded that while PCs can't normally open DMGs, there are third party programs for PCs that allow this.
But are my conclusions correct?
