How persistent is persistent storage?
MHP and OCAP make no guarantees about how long a file will remain in persistent storage. It may stay there for years, it may get deleted within a few minutes, or anything in between. The main reason for this is to give the receiver a way of managing storage, so that one application can’t use all of the space in the persistent storage and prevent other applications from storing anything.. For this reason, applications can’t assume that a file they stored in persistent storage will still be there. Some receivers are known to delete files in persistent storage when the power is cycled, and so it’s best not to rely on persistent files for storing personal information or information about customizing an application.
