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:
The parts of the default naming rule are defined as follows:
Identifies the name of the source document without the file extension.
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.
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.
