I’ve used this site for about two months and I love it. More than anything, I was looking for a place to host common media files that I was working on with my websites and client sites. This site solved it all for me. They give me 25gb FREE which if you’ve dealt with box.net, you’ll know that it’s significantly better.
They offer file management, photo, music, and video sharing just like the other ones and can host a large multitude of files (zip and psd too). So check them out if you need online file storage.
