Hi Danielle,
Oxygen 18.1 (which we plan to release in about a week) will come bundled with a default DITA refactoring action which replaces all topic IDs with the file name. Basically, you will open the main DITA Map in the DITA Maps Manager view, right click, choose
Refactoring->XML Refactoring and you will find two DITA-related predefined actions, one of which is called
Change topic ID to file name. The refactoring actions also have a Preview which allow you to see what the action will be doing before making changes on disk.
If you are using Oxygen 18.0 I can also provide you this refactoring action so that you can install it in your current Oxygen installation. So if you do not want to wait for the release just drop us an email (
support@oxygenxml.com)
Regards,
Radu
