Ahhh, I see.
I downloaded the 6500 file, and extracted it. Not by run the exe-file directly, but with use of 7 Zip. It's a superb software.
(Right click and open, os simply 'send to')

I seem to remember it was zipfiles, but I think the exe was to ekstract the files stright to floppy or SD-cards. 🤔

Here is the first in 6500 category extracted and zipped.

Someplace on one or another external HD I have tons of Technics stuff like styles etc. Maybe some of the days during the loooong and cold winter I'll go through it and see what to find.......

PS, if I remember it correctly, when use floppydisk the files must be in root, not in any folder.
