AutoCleanFolder is described as 'Automatically cleans up your folders for you on a regular basis, deleting files that haven't been accessed for a long time' and is an app in the OS & Utilities category. There are four alternatives to AutoCleanFolder for Mac, Windows and Electron / Atom Shell. The best alternative is DaisyDisk. It's not free, so if you're looking for a free alternative, you could try Automator or Space Radar.
With DaisyDisk you can free up disk space by quickly finding and deleting big, useless files. The program scans any mounted disk and displays it on the sunburst map, where segments mean files and folders, proportionally to their sizes. The map is easy to read and navigate.
With Automator, you can accomplish time-consuming, repetitive manual tasks quickly, efficiently, and effortlessly. Automator lets you skip the complex programming and scripting that is normally required to create automations.
