(+) What is an ISO file and What Can I do With It?

The following is a Plus Edition article written by and copyright by Dick Eastman.

Those of us who have been using computers for some time have become accustomed to a variety of file extensions. A file extension is the series of letters that is added to a file name after the period. It is often three letters long although it could be longer or shorter. In the Windows world, a file extension of .EXE indicates an executable file (a program), while .ZIP indicates a file that is compressed in ZIP format, .MP3 is a music file, .TXT is a text file, .DOC indicates a word processing document in the format used by Microsoft Word, .JPG is a graphics file, and so on.
