Automatic deletion
There is a maximum number of articles that is allowed to be stored. During Update, when that limit is
reached, the oldest articles on the device are automatically deleted to make room for newer articles
being downloaded.
A feed can be protected from automatic deletion by selecting "Properties" and then turning
off "Allow auto-deletion of articles during Update."
The maximum number of articles allowed can be changed from "Settings"
-> "Cache" -> "Total maximum number of articles stored"
