Comment 1 for bug 1713610

If I remember correctly we wanted to keep the reference in admin interface to alert mahara admin that they need to talk to sysadmin about why the file has gone away - as this could happen when dataroot is on a different server/partition and it's going away was a mistake/temporary.

So we need to have some sort of mechanism to be able to choose / delete rows from the list where we prompt 'are you sure' for lines that still have the archive but no prompt if the underlying file has gone away.
