One important point to understand when using screenbook files with other programs is the role of the xml master files: sbook.xml (in the screenbook folder) and sbooktoc.xml (in the bookshelf folder). Each time you create or edit a screenbook using Screenbook Maker, the following events take place.

• Screenbook Maker saves the screenbook text and links to the PNG screenshot files in sbook.xml.
• Screenbook Maker generates the HTML files for the screenbook from the bookshelf XSLT files.

A similar process takes place when select Regenerate Table of Contents from the Bookshelf menu.

In other words, the HTML files of a screenbook are derived files and are overwritten by Screenbook Maker. So, any changes you make to the HTML files with another program will be lost. In order to edit the HTML directly, you must copy the HTML files to another folder. (Screenbook Maker does not overwrite the PNG files unless you take a new screenshot, so you can safely edit these with the graphics program of your choice).
