certainly you can copy one card to another just by just dragging the contents to a temp folder on pc and then dragging them to the blank card, this was described in my book as soon as the 7k came out. It will work for the PRIVATE, SD-SOUND and IMEXPORT folders but do not bother to copy the SD_AUDIO folder, you need Jukebox to load audio to the new card. Inside the KN7000 folder you can also drag single customs to the CUSTOM folder, and fill it with single customs or change single customs even on a saved card since this does not affect the index files.
