Boundary ID files are used to store the ids of the nodes on all of the nodestrings in a mesh. The idea of this file is to export only the boundary ids. To do this, make sure nodestrings only exist along the boundary.
Boundary ID files are not opened in SMS but are saved from File | Save As... from the Mesh module.
