As the title states, I'm looking for working alternatives to Dropbox that don't involve using a VPN. I'm about to change jobs soon, to work with a UK based trader, and look after all his technical stuff. We'll need to have ways to host and share 3D CAD files. He's been using Dropbox with his Chinese assistant up to a couple of weeks back...and now has to email files back and forwards which is bloody inefficient. It will be worse with CAD data as the filesizes can get quite big.

I'll be using a Windows based system while he's on Macbook. So need something platform free.

Couldn't find any advice on the recent topic about DB being blocked.

Thanks in advance.
