Bert,
When I look in my "Band In A Box" subfolder, this is what I see ...

... and when I look in one of the folders off this, this is what I see (I've used "Piano" for the example).

Hope this helps,
Noel
When I look in my Band-in-a Box subfolder, I see exactly what you do ---- except that a) I have no "Woodwind" folder and b) I also see the all the Hi-Q (.tgs) files plus corresponding .txt files. That's because I manually copied them there in my efforts to get them recognized by SampleTank. I think that I copied them from d\bb\dxsettings.
When I look at one of the subfolders (ie - Piano), I see what you see.
