The Disk Drive
What is a File?
A floppy disk records documents as a sequence of coded data in the form of magnetic
signals on the disk's surface. The collection of data that makes up a particular document
is known as a FILE. Since there may be many different documents saved on a floppy disk,
each one must be given a FILE NAME so that you can see what files are on the disk, and
retrieve the one you want without having to read every one on the disk
A file name consists of up to 8 characters, followed by a 3 character code called the file
name extension. The extension is used by your machine to identify what kind of file this
is. For example, TEXTFILE.WPT is a Brother wordprocessor file.
When you are giving your files names, you do not need to worry about the extension, it
is added automatically by yourtypewhter. The only characters that are allowed in file names
are letters Ato Z, numbers Oto 9 and the hyphen (-). Yourtypewriterdoes not distinguish
between upper and lower case letters in file names, and letter input will be converted to
upper case.
If you try to input an invalid character, or type more than 8 characters in the file name, a
warning beep will sound.
When you have to cany out operations that involve loading files into memory, a list of files
will appear on the screen. These screens are known as index screens.
File names should be chosen so that you can easily find the document you want on the
disk You may wish to use names that are mnemonics, or arranged in alphabetical or
numerical order.
