I would like to store a few thousand PDF files and few thousand excel files externally from my computer. I would like to be able to easily and quickly access these files from my computer. Is it possible for someone a few hundred miles away to also get access to all of these files from their home computer? Is what I am looking for a server? And if so, does anyone have any recommendations besides Apples offering... as it seems expensive. Edit: Also, while using some of the excel files on my computer, I will need them to be able to grab information from other excel files sitting on the "server" or whatever device I need.
