Determining disjoint meshes islands

OK, maybe “disjoint” is not the best term, because what I’d ultimately like to know if a mesh is composed of various islands or one unbroken chunk.
Maybe the picture below will explain what I mean.

Using Disjoint Mesh just decomposes it back into its four original components, where I’d like to see the answer be two in this case…

Instead of joining your 4 mesh boxes you could do a mesh Boolean Union then count the resulting pieces.

Thanks Daniel. I knew the answer would probably be so simple I’d regret asking.
