The Installable File System (IFS) is a filesystem API in MS-DOS/PC DOS 4.x, IBM OS/2 and Microsoft Windows that enables the operating system to recognize and load drivers for file systems.

<operating system> (IFS or "File System Driver", "FSD") An API that allows you to extend OS/2 to access files stored on disk in formats other than FAT and HPFS, and access files that are stored on a network file server. For example an IFS could provide programs running under OS/2 (including DOS and Windows programs) with access to files stored under Unix using the Berkeley fast file system. The other variety of IFS (a "remote file system" or "redirector") allows file sharing over a LAN, e.g. using Unix's Network File System protocol. In this case, the IFS passes a program's file access requests to a remote file server, possibly also translating between different file attributes used by OS/2 and the remote system. Documentation on the IFS API has been available only by special request from IBM. An IFS is structured as an ordinary 16-bit DLL with entry points for opening, closing, reading, and writing files, the swapper, file locking, and Universal Naming Convention. The main part of an IFS that runs in ring 0 is called by the OS/2 kernel in the context of the caller's process and thread. The other part that runs in ring 3 is a utility library with entry points for FORMAT, RECOVER, SYS, and CHKDSK. EDM/2 article (http://edm2.com/0103/). (1999-04-07)

The File URI Scheme is a URI scheme defined in , typically used to retrieve files from within one's own computer.

<file format> The kind of data stored in a file. Most modern operating systems use the filename extension to determine the file type though some store this information elsewhere in the file system. The file type is used to choose an appropriate icon to represent the file in a GUI and the correct application with which to view, edit, run, or print the file. Different operating systems support different sets of file types though most agree on a large common set and allow arbitrary new types to be defined.
