-+- Quick Guide To File Extensions v1.0 -+-
-+- By Mark Klocek -+-

Introduction
------------
Files  are  often  named in different ways to help tell us what they are.
Often  file extensions are used, these are little names after the name of
the  file.   For  example  this  file was called FileExtensions.doc - The
first  part  before  the  full stop is the name of the file and after the
full stop is what type of file it is.
    File  extensions  are  used  widely  in  the computer world so we can
quickly  tell what type of data is contained in a file.  They are usually
short about 3 letters though 5 letters occurs occasionally.
    There  are  almost  certainly a load missing, so mail me on Channel X
BBS and it will be updated.
