A data file containing a written report can’t do anything by

itself. On the other hand, a word processor is useless without

documents to work on.

Filenames and Extensions

Needless to say, each file on a disk must be uniquely

identifiable. To achieve this, MS-DOS requires that you name

every file you create, as you create it.

In order to be able to manipulate files easily, MS-DOS has

certain rules that you must follow when naming files. As you

will see, these rules leave you a great deal of freedom in your

selection of filenames.

Each filename can be up to eight characters long. To this eight

character name can be added an “extension”. Extensions

always begin with a period ( . ) which is followed by up to three

characters.

The format for a valid MS-DOS filename is:

ABCDEFGH.JKL

Most of the characters and symbols on your keyboard are

available for use in filenames. These are:

The letters A through Z

The numbers 0 through 9

The following symbols:

(exclamation point)

(“at” sign)

(number sign)

4-20
