Audrey, if you see the files at the PC (the TFLD files) and you can't see them at the KN7000, it means that you have not copied the KN7000mn.inf file with the KN7000 folder, or the .inf file is corrupted. The KN7000mn.inf file contains, among other things, an index of all the files including the long names that you have given to each style or song. The integrity of that file is paramount. It must be copied as a part of the KN7000 folder along with the TFLD files. So, when styles are copied to a SD card with Windows Explorer of the PC, the copy must contain the complete KN7000 folder with all the TFLD files as well as the KN7000mn.inf file.
