Dec. 26/12 I did try as suggested. It couldn't find the file with the database in it. When I typed it in anyway, it gave me a scary message to send to the author, which I didn't do (or know how to do) ... because I was really doing something probably illegal. Then it ran for hours as if it was really doing it. I finally cancelled it.
However, I did go into the program.... 1. opened the default db. (it only had two cards in it) 2. I then opened the huge db.hundreds of cards in there. 3. selected all those cards as active and then used 'save as'. When it asked for place to save, I sent it to the default.db. It said it would override any card of the same name? but as I only had 2 cards in there and they were probably also in the huge one I was saving, I said yes. It did take a fair while to save it. But I'm smiling....
It appears to be working. One or two of the cards say media missing and I just check the default_media.db, and lo and behold, that sound file is not there. I go off to the original source copy and paste it into the default-media.db. Then it also gives me the sound.
Am having a wonderful learning time. Gone way past where they (it) wants me to stop. Thank you for your help and your wonderful program.
Have lots more questions for another time.
P,S.: regarding learning history.... I had just downloaded the 2.2 after deleting the 2.0 so there was no meaningful learning history.
