Computers store information on disks in files. A file is a collection of related information such as a computer program or the text of a letter.
Each file is given a unique name, and each filename is stored in a directory. To find out about the files in a directory, use the MS-DOS command DIR.
When referring to a file, you must use a file specification. This consists of a pathname, a filename and an extension (if there is one). As an example, to reference a file on drive B: called FRED.BAS (where the default drive is ‘A’) the correct file specification would be:
B:\FRED.BAS
