You can combine two Personal Knowbase data files using the Import command (from the File menu):
- Open the data file that you want to merge into.
- Select the Import command from the File menu.
- Specify Files of Type as Personal Knowbase Files (*.kno).
- Select the file you want to merge into the currently open file.
- Click the Open button.
You can then specify one or more keywords to assign to all of the incoming articles from the imported file (for example, to identify their source as the other data file).
See PK’s Help system for more information on Merging Data Files.
