and drop-off files to non-Zima users.
 

Anyone may perform the following activities:

Drop-off
Drop-off (upload) a file for a Zima user (email verification required).
Pick-up
Pick-up (download) a file dropped off for you.
 
Zima users: you may login with your username and password and send files to anyone, in or out of the Company.
Non-Zima users: you cannot log in, but can still send files to Zima users if you know their email address. Start by clicking the "Drop-off" button.
Zima users who wish someone outside the Company 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.
 
SendTo is a service to make it easy for you to move files, including large files up to 40.0 GB, in and out of the Company.
 
How secure is SendTo?

Files are automatically deleted from SendTo 14 days after you upload them.
