You can remove text-only topic files (.TXT) if you no longer need to use them with your context-sensitive Help. For example, if one of your .TXT files pertains to a group of dialogs that are no longer used in the application, you can remove the text-only topic file from the project.
Click the Project tab.
Open both the Context-Sensitive and Text-Only Topic Files folders.
Select the text-only topic file (.TXT file) to remove.
Click Delete
.
Open the Map Files folder.
Select the map file (.H) that is associated with the .TXT file you just removed.
Click Delete
. Both the text-only topic file and its associated map file
are removed from the project.
Compile your project to update the .CHM file.
