Boundshape.nif ?

[Xyth]

I have many of these files scattered throughout all the unit art in my mod. They're tiny so I'm not too worried but I'm curious what they are for. There seems to be no ill effect in game or in NifSkope if I delete them - is there any reason to keep them?

EDIT: Far few boundshape.tga as well
EDIT2: And what about all these extra .nif that have freeze103 (or similar) in the name?

It has to do with NifViewer. NifViewer occasionally has problems reading some nifs if they don't have a boundshape.nif and boundshape.tga in the same directory.

As for the freeze nifs, I think those are for people with frozen animations checked, but I'm not entirely sure.

thery are used for this (but linked to the kfm and not the nif by name).
