This section explains the difference between the different types of page groups and why it is important to make the right choice.
You can add a page group into any folder by clicking on the folder and then clicking on 'Add page group'.
This is the menu that appears:
To understand the differences, we need to:
A web page is another name for an .htm or .html file. This stands for Hypertext Markup Language and is the language used by web browsers. Internet Explorer is one browser, Netscape Navigator is another. A web page written in .html can be viewed directly using a web browser. This is why when you 'view' 'any other type of file' it has to download into that application on your computer. 'Any other type of file' is not a web page, and is therefore cannot be understood by a web browser.
The web page below is a combination of two files:
the web page 'sample_web_page.htm'
and the image 'heron.gif'. There is a link from the web page to the picture telling the browser to insert the picture. The web page and the image are two separate files, brought together by the browser.
If you delete the image from the folder, you would get this:
The browser goes to get the image, but it's not there. Hence the little
symbol 
or 
showing a broken link.
This table shows how an application creates its own file, and how this then appears as a web page. The fourth column then categorizes what sort of web page this is for uploading onto Webstore:
| Application | Its own file | The web page(s) | Webstore category |
|---|---|---|---|
| Word 97 |  |
|
Web page without a subfolder making the heron example. |
| Word 2000 Setup 1 |
 |
 the sub folder contains these files:  |
Web page with a subfolder making the heron example. |
| Word 2000 Setup 2 |
|
 |
Web page without a subfolder making the heron example. |
| Publisher 2000 |  |
 |
Web page without a subfolder. This is a website with two linked pages, each with a picture. |
| Frontpage 2000 example 1 |
Saves as web pages | |
The same because Frontpage only works on web pages. The advantage is that you can use it to edit web pages directly that have already been created. |
| Frontpage 2000 example 2 |
Saves as web pages |  The image folder contains:  |
Sometimes users of Frontpage (and other software) choose to put all the images into a sub folder called images. |
Therefore the upload page menu is explained like this:
Advanced pages are the same as Novice pages except they don't have any help. This means you can collect the files without having to move down the page so much. i.e. it's quicker.
| Web Page (or linked web pages) without subfolder | All the files are together in one folder. Examples of a single web page are Word 97, Word 2000 setup 2 and Frontpage 2000. Publisher gives an example of linked web pages without a subfolder. |
| Web Page (or linked web pages) with up to three subfolders | Word 2000 setup 1 gives an example of a web page with a subfolder. Frontpage 2000 example 2 gives an example of linked web pages with a subfolder. |
| Any Other Type of File | This is for a single word document, or a single excel file. | Multiple Files | This is for uploading a number of word documents or a number of excel files. | Web Links | Open a web page in a new browser window |
