Burn To The Brim Help
  If you wish, BTTB can move the found solutions to a folder for easy copying/burning. If you select this option BTTB will put them each in their own subfolder within the folder you can select with Set. Each group will be put in a numbered folder, starting with 1 (already existing folders will always be left untouched). Folders are named <Prefix><Counter><Suffix>, where counter has at least Min # Digits digits. An example of your selection is always shown.
