A BTree is a balanced tree data structure that behaves like a mapping but distributes keys throughout a number of tree nodes. Introduction to Zope BTrees? aren't quite like this, but you'd have to pick Tim's brain to find out how they differ.
These are provided by the BTrees package included in Introduction to Zope.
Use these instead of python dictionaries when a mapping may be large.
A BTreeFolder? is a BTree-based folder, useful for managing many objects. Nowadays, people use the BTreeFolder2 product to get hold of these.

The [API documentation]:BTrees.html link goes off to some issue tracker. I don't think that's what was intended.

You're right; I've removed the stale Remotewikiurl link on API documentation, avoid '[API documentation]:something'-type links for now.
