The folders that I have were set up by the BIAB install.

Under RealTracks there is a Loops folder.

Under that folders (Loops), there are 2 other folders.

Nature Sounds and Percussion Loops

I do not know if they specifically need to be there by those names.
You can see them in the picture if you look at my web page.
Perhaps you could create them and put the claps in the precussion loops folder...
