I use Epic Editor to create dita files. Here's a problem I came across recently:

I created a concept topic and saved it as c_admin.dita. While the file is still open, I saved it as another file c_client.dita and changed the concept id. I created a totally new content for c_client.dita and saved and closed it when I finished, believing I had two concept files now.

 When I opened c_admin.dita again, I found I lost its original content---c_admin.dita has the content of c_client.dita! Even though both files have different file names and ids, their contents are exactly the same.

 Can anyone of you tell me what I did wrong? How can I restore the original contents of c_admin.dita? Or, did I lose it permanently?

 Thanks!
