Login
Rigaku users should login first.
 

Anyone may perform the following activities:

Drop-off
Drop-off (upload) a file for a Rigaku user (email verification required).
Pick-up
Pick-up (download) a file dropped off for you.
 
Rigaku users: you may login with your username and password and send files to anyone, in or out of the Corporation.
Non-Rigaku users: you cannot log in, but can still send files to Rigaku users if you know their email address. Start by clicking the "Drop-off" button.
Rigaku users who wish someone outside the Corporation 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.
 
SFTP is a service to make it easy for you to move files, including large files up to 20.0 GB, in and out of the Corporation.
 
How secure is SFTP?

Files are automatically deleted from SFTP 30 days after you upload them.
