I get heaps of traffic to one of my web site pages which is all about how to make an ebook from an exe file and how to make an PDF ebook without Adobe Acrobat.
I have just come across another great little free application which will convert your HTML files into an exe ebook.
Here is what the creator says about this product.
WebSiteZip Packer - free and easy-to-use application which will help you to turn a single HTML page or a group of pages into a solid executable file (.exe) with an integrated HTML browser. Ideal for e-books, product catalogs, site demos, manuals, and searchable information distribution.

After using our WebSiteZip Packer you can conveniently transport your HTML page or a complete web site as a single file embodying all necessary components (graphics, sounds, linked pages, etc.) and present it successfully independently of the type of HTML browser installed at the destination computer.
These are possible uses of WebSiteZip Packer:
*Use it to produce and distribute e-books;
*Let the visitors of your web site download the identical exe-version of the site for offline work;
* Create convenient offline presentations and catalogs;
*Create guides and manuals for your software products;
*Use it for any purpose where you need a solid executable file with an integrated HTML browser instead of piles of separate files and folders which are usual attributes of HTML pages.
