Sometimes a document is so secret that once locked away, it can only be viewed once a deputy has unlocked it.  An example of this would be something like your grandma's secret cake recipe, or the codes to a nuclear warhead.

If the person you are deputising requests a file unlock, you will receive a notification in your email.  Login, and you will see the following in your Deputy vaultbox.

Click Approve or Reject as appropriate.  Note that approving a file can take a little while, so please be patient!

Only one deputy is required to unlock the file, so once you have done this, the file is available to be opened.
