I found the easiest way to send large files, short of mailing a DVD, lol is this website.
How to Send a File | SendThisFile
It is not a spam and it does work. I have personally used it to send large files, survey reports, etc. Works by sending to and email address, only downfall is the recipient only has 3 days from the time they are emailed a notification, to download the file, or it is deleted. And the free version is super slow to upload, can be over an hour for a file the size of the manual.
But if you want to invest an hour to upload, it does work.
