a bit about FILES

On your computer, everything is stored as a file.
Every file has a file extension that tells the world what kind of a file it is.

file name `--->` `diary.txt` `<---` file extension

> A file is simply a packet of information such as a picture or a document. If you want to organize your files and put them into nice neat little groups, you'd use some folders. Folders don't come with file extensions because because they're not files.

> If your file extensions are not all showing, you can do the following to make them all magically appear...

> 1. In any window (like the one above) click View.
> 2. Click Options...
> 3. Click the View tab
> 4. Click Show all files
> 5. Make sure the Hide MS-DOS File Extensions box is not checked.
> 6. Click OK

> `.txt` is a plain old text file; `.gif`, `.jpg` and `.bmp` are image files; `.mpg` and `.avi` are movie files; `.doc` and `.wri` are formatted documents; `.exe` is an application or program; and `.html` or `.htm` are commonly known as HTML files. They are the backbone of Web Pages. You will be making a few very soon and you'll be surprised at how easy it is!

Now let's get back to the tutorial!
