Problem
You confirmed the deletion of a file in the Document Centre and now want to undo it.
Possible cause
Deletion is permanent — there is no undo function in the system. The confirmation dialog requires a deliberate action, but mistakes can happen.
Solution
Contact your administrator to ask whether the file can be restored from a backup on the server.
In future: read the confirmation dialog carefully before clicking the red Delete button.
If the problem persists, contact support and include details about:
The file name of the deleted document.
When it was deleted.
