If you are a PSI Cloud user, you should login above to avoid having to verify your email address,
and be able to drop-off files to non-PSI Cloud users.

Anyone may perform the following activities:

Drop-off
Drop-off (upload) a file for a PSI Cloud user (email verification required).
Pick-up
Pick-up (download) a file dropped off for you.
 
PSI Cloud users: you may login with your username and password and send files to anyone, in or out of PSI FileXchange. Ask PSI support for an account.
Non-PSI Cloud users: you cannot log in, but can still send files to PSI Cloud users if you know their email address. Ask your PSI contact for a valid PSI Cloud user. Start by clicking the "Drop-off" button.
PSI Cloud users who wish someone outside PSI FileXchange 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.
 
PSI FileXchange is a service to make it easy for you to move files, including large files up to 500.0 GB, in and out of PSI FileXchange.
 
How secure is PSI FileXchange?

Files are automatically deleted from PSI FileXchange 5 days after you upload them.
