Computer file

A computer file is a means to store information that belongs together. Computer files can be opened (read and written) by computer programs. Usually they are stored on some kind of file system.

There are different kinds of computer files that hold different kinds of data (information):

Text files
Audio files (e.g. for songs, voice recordings)
Video files (e.g. for movies)
Images (pictures)
Other binary data

The way the information is organized in a file is called the file format.
