Removing a program’s Application Support folder is a good way to reset the program to its default state and force a clean start. When users access this folder, it’s to change the way a program works in a way that is unsupported by the default settings or to fix some kind of cache or database error. Away from the user’s data folders, these files can be segregated to avoid contamination or modification. Here, applications save files needed for their operations. The “~/Library/Application Support” folder is the most frequently accessed Library folder. These files save preferences, application databases, metadata, plugins, saved application states, system profiles, cookies, and much, much more. You’ll find a huge variety of files and folders in both the user Library folder (found at “~/Library”) and the system Library folder (found at “/System/Library”). Applications are basically free to do what they like when it comes to placing files in the Library, but most follow a fairly similar process. To be frank, the organizational process here can be a little chaotic. They are created by applications, and applications add, remove, and modify files over the course of their operation. Library Folders: /System/Library and ~/Library If you must experiment, make a bootable clone of your Mac before proceeding. You can browse safely, but adding, removing, or modifying files or changing the folders themselves can have unpredictable – and sometimes system-breaking – consequences. Note: Do not add to, remove, or modify system folders and files. We will first look at its contents before moving on to other, deeper system folders. The “/System” folder itself on your Mac doesn’t contain much. But what are the different system folders for? What’s “bin,” and how does it help your computer? We will examine the most commonly-referenced system folders below.
