Automatic Deletion

The HSD Versions Cleaner performs automatic deletion of old file version snapshots without any interaction with the user - it just works in the background. As soon as the HSD Versions Cleaner has been started and automatic deletion is enabled for at least one imported root directory, automatic deletion of old file version snapshots is active, which means it is waiting for certain events. It is not required to have the app’s window open for that (if it is closed, you can reopen it simply by clicking the app’s icon on the dock). Automatic deletion of old file version snapshots even works if the system has sent the HSD Version Cleaner to sleep (the so-called  App Nap ; but note that automatic deletion stops working if you terminate the app).

Which old file version snapshots will be deleted automatically and when this happens depends on various criteria settings that can be set for each imported root directory. The HSD Versions Cleaner works closely with the system: most of the time, the app is sitting on the dock snoozing (unless you are interacting with the app, of course). In simple terms, the HSD Versions Cleaner asks the system to be informed when certain events occur. As soon as the app receives such a requested information from the system, it processes tasks like automatic deletion in the background. Having done that the app may request some new information from the system before it falls asleep again, waiting for the next call from the system.

There are, however, some situations in which automatic deletion of old file version snapshots will be interrupted:

In all these situations, as soon as the HSD Versions Cleaner restarts or awakes again together with the Mac, automatic deletion checks if there’re any old file version snapshots that have expired in the meanwhile and deletes such old file version snapshots immediately.
