Div Share. These guys might not have the greatest business sense (they offer all of the above completely free 8O), but they have a great product. We do a lot of work using huge CAD files. When we are ready for the client to review the CAD file, we upload it to our servers and email them a link so they can download and view. These files typically end up occupying a ton of space on our servers. Now, we can clog up Div Share’s servers if we want. Very nice! Thanks to Rick at Lifehacker for sounding off about this!
