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.
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 (or directories). Folders don't come with file extensions because because they're not files.
If you're running Windows and your file extensions are not all showing, you can do something similar to the following to make them all magically appear...
Windows95/98/ME/XP etc... |
- In any window (like the one above) click View.
- Click Folder Options...
- Click the View tab
- Click Show all files
- Make sure the Hide File Extensions for known file types box is not checked.
- Click OK

.txt is a plain old text file;
.gif, .jpg and .bmp are image files;

.doc, .wri and .rtf are formatted documents;
.exe is an application or program;
.wav and .mp3 are audio files;
and .php 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!
