DOS file names/ extensions/functions

DOS has several functions, all you have to do is type it correctly and you'll get those functions to work.
Examples of DOS functions :

• Formatting(preparing) and organizing a disk for use.

• Setting up subdirectories and directories.

• Running programs on your computer.

• moving and copying files.

The following will be of use when creating directories/subdirectories.

• Formatting - so that you can prepare a disk for your use

(some times disks are formatted in a drive that is not readable by your computer system, thats when formatting comes into play)

• Copy- exactly what it means, its to copy files on your computer onto other drives, folders, etc...

• DIR- stands for Directory, you can type this in the command window and get a list of the names of files on a given disk.
  

• CHKDSK - this allows you to check the characteristics of the disk and system.

These were just a few examples to get us started on DOS.
