Holy crap, there are a lot of file-sharing services out there! Mentioning another always feels a little redundant, but Jumpshare offers several advantages that make it worthwhile. No accounts are required, it works via drag-and-drop, and just about anything you upload can be viewed right from the browser.
Jumpshare supports over 150 file types. This doesn't refer to what you can upload — you can upload pretty much anything — but rather what Jumpshare will understand and display in the browser. For example, if you upload a Word document or movie or song and share it with people, they will be able to view it right in their browsers without downloading it to their computers. This is really useful if you're sharing a file that recipients may not be able to open on their end.
Additionally, Jumpshare allows you to send links to your uploaded files before they've finished uploading. This is a feature we really liked with another file-sharing service called Ge.tt, but Ge.tt has fewer features, and many users have complained that it's a little bit slow.
The lack of accounts and wait time, plus extremely comprehensive file-viewing support, make Jumpshare a really compelling choice when you need to send files online. The only disadvantage is that your files disappear after two weeks. But so long as you don't need an infinite link, there's a lot to like.
