Explanation of the DEL (ERASE) command. It is INTERNAL.

This command lets you erase one or more files in a directory.

Example:
       To erase the Test.Bat file on drive A and be asked for
       confirmation before erasing this file you just type:
          del a:test.bat
       
       To delete a whole group of files in the same directory
       you just type:
         del a:*.*
       Del will ask for confirmation on this command automatically.
