The first time you publish, the default destination location is set to the My Documents folder on your local computer. You can change this either by browsing to a new location or typing a path. If you change the location, it becomes the new default location for the next time you publish.
It is essential to understand the importance of the destination location when you publish content.
Publishing settings
The first time you publish to a specific destination location, the Developer saves the publishing settings you used to that location. These settings include the output formats that were published and the options for each individual format. Each time you publish to that same location, the settings in the Publishing Wizard will reflect the ones specified for that location. You can change the options as necessary each time you publish to that location, and the changes are saved for the next time you publish.
Incremental publishing
Incremental publishing allows you to update published content quickly. When you publish content to a destination location, the Developer records the publishing data. When you publish the same content to the same location, the Developer accesses the publishing data and only the changes are published, including new content, changes to the existing content, and deletions. Because only the changes are published, the publishing process is much faster. Therefore, if you want to publish the changes to an outline, you publish the entire outline without having to select individual items in the outline structure.
Replace Published Content
If you choose to publish a different content selection to a destination in which you have already published, the Developer will warn you and ask you whether you want to replace the old content. If you continue, the result depends on the type of format to which you are publishing:
