Ok - you've got two different approaches to providing you with style sets.
The first you mention - PRIVATE > TECHNICS > KN7000 > TFLD001 > - are a whole collection of styles bundled up into a file which can only be unbundled and loaded onto an SD Card using a bit of computer software called SD Explorer for KN7000. You would also need a bit of kit called a Panasonic SD USB Reader/Writer and you insert a blank SD Card into one end and attach the other USB end to your computer. The SD Explorer software will enable you to 'RESTORE' the above mentioned .sdb bundle to the SD Card.
Willumspages which includes a good few of my song specific style files along with all of Bill's work. The components of a single style file set are a set of ACT CMP LSW PMT SQT TM files. Let's say the song was 'Lover' (my invention of a name for a song) then you would download lover.act lover.cmp lover.lsw etc to a floppy disk and take that floppy disk over to your KN7000 and load it into your keyboard. A floppy disk can hold (1.44mb) about 7 or 8 sets of those style files, and you can download them to your keyboard one set at a time, remembering to save that downloaded set to an SD Card before downloading the next one.
