The classic Macintosh system folder requires certain files and directories in order to function properly.
A system enabler file is placed in the root of the System Folder and is required on certain Macintosh models, typically when the Mac OS version is older than the hardware. A 1994 list of required system enablers can be found at Latest System Enablers List (June 1994).

This is a directory found inside the Extensions folder and contains the various voices being used by the MacinTalk software.
Since System 7.1, fonts have been stored in the dedicated Fonts folder. A default Mac OS install will include a handful of fonts, and you can place additional fonts in this folder.
Help related documents for Apple software and some third-party titles will place their files in this folder. It is assumed that nothing in this folder is needed for actual OS operation.
This folder contains modules for AppleScript to assist in creating scripts. Previous to Mac OS 8.x, this folder was located inside the Extensions folder.
Items in this folder are automatically executed after the Finder has loaded. This may be any application or document, and the system will treat it as if you were just double-clicking on it in the folder.
Items in this folder are executed before the Finder fully unloads during a restart or shutdown. This may be any application or document, and the system will treat it as if you were just double-clicking on it in the folder. As the system is about to shutdown, usage for this might be limited to things such as data backup scripts or "exit" sounds.
