Computer file

A computer file is a resource for storing information, which is available to a computer program and is usually based on some kind of durable storage. A file is "durable" in the sense that it remains available for other programs to use after the program that created it has finished executing. Computer files can be considered as the modern counterpart of paper documents which traditionally are kept in office and library files, and this is the source of the term.

Etymology

The word "file" was used publicly in the context of computer storage as early as February, 1950. In an RCA (Radio Corporation of America) advertisement in Popular Science Magazine describing a new "memory" vacuum tube it had developed, RCA stated:

In 1952, "file" was used in referring to information stored on punched cards.

In early usage, people regarded the underlying hardware (rather than the contents) as a file. For example, the IBM 350 disk drives were called "disk files". In about 1961 the Burroughs MCP and the MIT Compatible Time-Sharing System introduced the concept of a "file system", which managed several virtual "files" on one storage device, giving the term its present-day meaning. Although the current term "register file" shows the early concept of files, it has largely disappeared.

Filing (legal)

In law, filing is the act of submitting a document to the clerk of a court for the court's immediate consideration and for storage in the court's files. Courts will not consider motions unless an appropriate memorandum or brief is filed before the appropriate deadline. Usually a filing fee is paid which is part of court costs.

Filing systems

In civil procedure systems, filing rules can be mandatory or permissive. In a mandatory filing system, all documents of legal importance exchanged between the parties are also filed with the court, while in a permissive filing system, nothing needs to be filed until the case reaches a point where direct judicial management is absolutely necessary (such as the brink of trial).

For example, the United States federal courts operate on a mandatory filing system (with minor exceptions for the most routine discovery exchanges). In contrast, the U.S. state of New York is known for its permissive filing system, which was modified in 1992 but still largely operates in its traditional form in certain lower courts.
