Dropbox is great and all, but Chinese versions of the versatile cloud storage platform offer much more space (up to 10TB, even), and most of them are free too.
Because I am in China, even with my VPN Dropbox and Box.com don’t seem to work. When I found Weiyun, with 10 Terabytes of free storage I thought it was unreal. But it seems to work. Because it is in English, I would recommend this to anyone around the world. I am not sure if it would work though, because it asked me for a Chinese landline in order to connect the account.
