Thanks a lot for your suggestion. I finally am able to get rid of the non-using card type now.
One further issue is that if I have created some cards in certain card type and other cards under different card types name. All of them are of the same nature, for example, the front card is name a "term or word" and the back card is the "meaning of the word" but while I am creating the cards I just gave them some different card types name. Is it possible to consolidate all of them into one single card type and clean out redundant card type name.
As an illustration:
Now I have,
Card number 1 to 10, under card type named "ABC"
Card number 11 to 20, under card type named "DEF"
Card number 21 to 30, under card type named "GHI"
Card number 31 to 40, under card type named "XYZ"
and I want consolidate them into
Card number 1 to 30, all under card type named "ABC"
Card number 31 to 40, remain under card type named "XYZ" (as the template design is different from that of "ABC"
will there be an option to alter the card type of certain cards to get the above result?
I find there is option to rename a card type name and i have tried to rename card type "DEF' and GHI" into "ABC" but it ends up with 3 card type name as "ABC" in 3 entries in the "choose card type" dialogue box.
