(There's no video for File System Manager 1.2 SDK yet. Please contribute to MR and add a video now!)
The File System Manager is the part of the Macintosh Operating System that manages the use of foreign file systems. The File System Manager provides a general means by which foreign file systems can be installed, identified, and interfaced to the Operating System .
For each installed file system, the File System Manager maintains a file system descriptor (FSD). Information in the FSD identifies the file system and describes its interfaces to the File System Manager and to the FSM component interfaces supplied by the File System Manager. Installed FSDs are kept in the File System Manager'5s private FSD queue.
A foreign file system's FSD can be installed, accessed, maintained, and removed with the FSM service routines.
