Autopilot is a watched folder, not a timer

“Automatic cleanup” usually means a schedule. Something runs at night, applies a rule you configured once, and you find out what happened in the morning. Disk Housekeeper Autopilot is a different shape. It watches a folder you choose. Cleanup of that folder still goes through a preview, and removals still go to the Trash by default.

The name is easy to over-read. This note is the correction.

What is being watched

A watched folder is a location you have decided is fair game for the rules, not a scan of the whole disk. Downloads is a common choice, because it fills up with installers and exports you meant to file. A build-output directory is another, if you are sure the next build can recreate it. Your Documents folder is a bad default. Autopilot does not talk you out of a bad folder. You do, by not selecting it.

The use case Set up Autopilot for a watched folder is deliberately boring: pick the folder, know what the rule will match, read the preview, leave the result in the Trash until you have lived with it.

Preview does not become optional

Disk Housekeeper always previews before cleaning. Autopilot does not create a second mode where the preview is skipped. If you wanted a cleaner that deletes on a timer without showing you the list, this is not that cleaner. The preview is the product. The watch just means you do not have to remember to open the app when the folder gets messy.

Auto-Sort is the sibling feature, and it is not the same thing. Auto-Sort applies plain-English rules so files land in the places you described. Autopilot is watched-folder cleanup. You can use both. You should not describe one with the other’s verb. Sorting is a move you meant. Cleaning is a removal you should be able to undo from the Trash.

We do not document a rule grammar on this site. The product says the rules are plain English. An example you might mean is “installers older than a month,” but treat that as an illustration of the kind of sentence, not as a syntax we have published. The preview shows you what the app understood. Trust the preview over your memory of the sentence.

Low space is a separate signal

A low-space alert tells you the disk is tight. It does not by itself run Autopilot. The menu bar readout is the number. The alert is the nudge. The watched folder is the scope. Keeping those three apart is how you avoid “the app deleted things because the disk was full,” which is not the behavior we describe.

If you want the manual version of the same care, start with How to free up disk space on a Mac and come back to Autopilot when the folder you would clean by hand is obvious.
