Nice online storage/sharing application. It has 5GB FREE storage, and upgradeable with certain amount of fee. Available from http://4shared.com .
I like the Windows-Explorer-like interface. You could assign public/private mode for certain files or folders. Each file is provided with unique link. Each user can acquire a subdomain from 4shared.com.
However, each time I do something, the whole page is refreshed. It doesn't maximis the usage of AJAX technologies.
Upload is good. I tested with 25MB of zip files, and it took less than 5 minutes. I considered my internet line is medium fast.
Overall, I give 4 stars upon 5.
