A file system operates within the file server to provide services which deliver the required function to the client API. The elocal.fsy file system, a core part of the operating system, drives the local media—ROM, RAM and CF card. A VFAT file system is used in each case, which maps directly onto the client API.

Other file systems may be implemented, for example to support remote file systems over a network. Such file systems may be installed dynamically without any reboot. They may also be uninstalled dynamically, and so free up resources.

Installable file systems must present a Symbian OS native interface for clients, no matter what the interface and specification of the remote file system. This is trivial for Windows, OS/2 and DOS, since Symbian OS maps these directly. For Unix, minor changes such as swapping directory separators between / and \ are needed. For systems such as IBM's mainframes, and DEC's VMS, more radical mappings are needed, to transform between the remote file system's record-based architecture, and Symbian OS's byte-based architecture.
