Anyone may perform the following activities:

Drop-off
Drop-off (upload) a file for a Innoflight user (email verification required).
Pick-up
Pick-up (download) a file dropped off for you.
 
Innoflight users: you may login with your username and password and send files to anyone, in or out of Innoflight.
Non-Innoflight users: you cannot log in, but can still send files to Innoflight users if you know their email address. Start by clicking the "Drop-off" button.
Innoflight users who wish someone outside Innoflight to send them files, can make it a lot easier for them by logging in and clicking "Request a Drop-off". That saves the other person having to prove who they are. The request created will be valid for 7 days.
 
Big File Transfer is a service to make it easy for you to move files, including large files up to 300.0 GB, in and out of Innoflight.
 
How secure is Big File Transfer?

Files are automatically deleted from Big File Transfer 14 days after you upload them.
