So, I used JustBeamIt. With Justbeamit, you simply upload a file (drag and drop), get the private link and send the link to the person you want to share the file with. Leave the browser page open until the person downloads the file. The page will tell you when they have downloaded it.
No account sign up is required and it's very easy to use.
This is a great resource when you need to share a large file.
