tiny fbx file ballons to enormous max file...thoughts on why?

[fixeighted]

I've exported a load of map tiles from Blender as fbx files. They are all around 35mb but each in max is then around 300mb, which seems excessive.
The associated textures are a combined 230mb, so I can't figure out where the size comes from.
Any ideas?

It is probably compressed. If you use compress on save in 3ds max probably the size will be smaller.

EDIT: Don't worry, I figured out the process, within which I was missing a crucial step.
I had neglected to run a script to bake the tile's 18000 textures into one. Silly me
