tlbdata and setup files in folders

I note that TLB creates tlbdata.xml and setup.ini in the primary folder. Occasionally I find these files in nested folders, and delete them. That's because when I first found TLB and began dragging files and folders around, I managed to find combinations that were unstable.

TLB now works brilliantly on this Vista laptop, and I want to keep it that way. Deleting those files doesn't seem to make any difference, positive or negative.... I think.

Should I delete all but the primary folder tlbdata and setup files?[/i]
