Use the Project Manager to rename Help topic files (*.HTM). All references to the files are automatically updated, so your project will not include broken links.
WARNING! Project Manager does not automatically update the project if you rename files outside of the program. Therefore, do not use the Windows Explorer to rename files because the references will not be updated in your project, resulting in broken links, missing images in topics, etc. See Safeguarding your work for further information.
Click the Project tab.
From the View menu, select By Topic Title. (This is the default selection unless you've changed it.)
In the Project Manager, open the folder that contains the file to rename.
Right-click the file and select Rename.
Type the new name. (You don't have to enter the .HTM extension because the program will do it for you.)
Note: Avoid using these characters with file names: \ / : * ? < > | # "
Press ENTER. The file is renamed and all references to it are automatically updated.
Click Save
All to save all changes in the project.
Tip: When you rename a file, it might have an effect on other items in your project that are based on the name. For example, consider renaming the topic title, books and pages, and even some keywords.
