So why would you use an file-sharing app anyway? Actually for many reasons: for larger files, for privacy, multiple files, file format support, and more.
In this post, I compare 16 file-sharing services. I took three main issues under consideration when creating the comprehensive app list below: Free, Fast, and Useful . . .
Most of the services suggested require no registration. None of them will ask you to download anything to your computer, and all of them are easy to use, and worth using. It is actually great to see services, such as Yousendit, MailBigFile, and Rapidshare, that are still relevant and are good choices, but if I had to pick one it would be Mediafire.
