Hints to reduce fbx file size?

Hi,

i created a simple character with 21 bones in Blender, with an animation of 10 frames on the timeline, and the file size is “350Ko” when i only export the “Armature” in .fbx . Is there any way to reduce the size, because i’ll have to export around 50 animations, more or less with the same amount of frames (9-10), and this would end up with 17 Mo for the animations only… Any hint?

Thanks

Bump, got the same problem with mocap data and i’m looking for hint to reduce the fbx size which contain anim too.
