Disappearing Rich Text

After setting up a number of date-file templates (for journals, news, etc.) comprising a set of RTF documents, waiting for entries, I experienced a File error that required rebuilding the database.

Devon automatically rebuilt the database excellently.

However, all those painstakingly created RTF documents have become text documents.  Is there any way I can select a set of text documents and convert them to RTF?



The only way to convert them currently is to display each document, chosse "Make Rich Text" and save the document.

Thanks, Chris.  I kinda figured that was the solution.  
I appreciate your response.
