In computer terms, a 'file' is a chunk of data that is treated as a single item by the operating system. A file is given a name. For example MYDOCUMENT.DOC The name is used by the operating system to store and fetch the file. This one happens to be split into two parts separated by dot.
Files can be stored on various storage devices such as hard disk and memory stick.
