the only working desk top computer i have access to right now doesn't belong to me and im not sure if the owner will mind me installing programs off of the net to their computer. And our laptop is sort of on its last legs with barely any free space left so i think downloading dropbox will tip it over the edge. I'm thinking of using dropbox to transfer files from my i pad to our external hard drive for storage and also for access in artrage 4 (I also intend to install to and run the artrage 4 program from the external hard drive)

I know I have seen a previous post about installing art rage 4 to an external hard drive. but i can do the same with dropbox? I'm a bit clueless about the hardware and software running bit.

Thanks in Advance
