Understanding Default File Naming and File Extensions for Topics
ePublisher assigns a default file name for each topic in a source document by applying the following default naming rule:
source-name.file-number.topic-number
The parts of the default naming rule are defined as follows:
source-name
Identifies the name of the source document without the file extension.
file-number
Identifies the number of the source document in the order it is included in its containing group in the project, such as 1 for the first source document in a group and 2 for the second source document in a group. This value starts at 1 for the first source document in each group in your project.
topic-number
Identifies the number of the topic (output page) generated from the source document, such as 1 for the first topic generated from a source document and 2 for the second topic generated from a source document. This value starts at 1 for the first topic in each source document.
For example, if you have a MyFile.fm source document that contains three topics that start with a paragraph style that has a page break priority set in Style Designer, ePublisher generates the following default output file names: MyFile.1.1.html, MyFile.1.2.html, and MyFile.1.3.html. You can change the default file extension for each page style.
