Edit and Create Extension Modules
When building an extension, you should develop each area of functionality as a module and then store each module in the Modules folder of the extension’s Workspace directory as described in Extension Development Files and Folders.
When you follow the steps described in Create a Baseline Extension, the extension developer tools create an initial module for your extension. You can edit the starter files included in the initial module to develop the custom functionality you need. For more information about the initial module and the files it contains, see: Anatomy of an Extension and What Happens When You Create a Baseline Extension?
You can use the extension developer tools to create additional modules for your extension. For detailed instructions, see Create Additional Modules for an Extension.
