Requesting details about modding possibilities of skyrim's combat

What do you mean by "I am stuck"?

 

The tool usage says the following, if that's more clear. Instead of single .kf and animation hkx files you can provide folders that contain multiple files.

Usage: hkxcmd ConvertKF [-opts[modifiers]] [skel.hkx] [anim.kf] [anim.hkx]
  Convert Gamebryo KF animation to Havok HKX animation
  If a folder is specified then the folder will be searched for any projects and convert those.
<Options>
  skel.hkx      Path to Havok skeleton for animation binding.
  anim.kf       Path to Gamebryo animation to convert (Default: anim.hkx with kf ext)
  anim.hkx      Path to Havok animation to write

 

Well actually I solved that problem by watching other videos.

but I am now stuck at the point where 3ds Max has the "improper file format" message when I try to import the .kf files.

I already have the niftools installed
