I usually use "WeTransfer" to send large files - I like the design, no need to register, unlimited number of files, automated email to a friend or client with a link and download confirmation. The only "but" of wetransfer is the 2gb limit. I've made my own research to see what are the wetransfer alternatives and the best file transfer sites with greater file size limit. Here I post my own list - free services only, no registration needed, automated emails with links.
Design: clean and look much like wetransfer, but requiers few more steps to upload file.
Download confirmation: YES
How long file is on the server: 3 days
Nice feature: while you're entering all information (email addresses, subject, text) it already uploads the files
Apps: Android and AppStore - allow to upload up to 5gb with internet reconnect when using wifi
Design: everything is clear, but no beautiful background images
Download confirmation: YES
How long file is on the server: you can choose the number of days, but up to 7
+ multi-language interface, confirmation email is sent in language you've used during upload
Nice feature: you can have password protected page with your file (paid)
Apps: AppStore, Desktop (mac & pc) + Outlook addon, API
