Martha,
Have a look at these links from this Wiki topic
http://fox.wikis.com/wc.dll?Wiki~FileExtensions>I've run into files I don't recognize. I know there's data in there somewhere, I just don't know how to get at it. Best I can tell these are Btrieve files (DDF's). Is there a way to pull this info into a Fox compatible format? If so, can you point me in the right direction?
