How to insert VTF file back into VPK file?

[Lord_Horris]

I just extracted the VTF file for a prop from hl2_textures_dir (using GCFScape) to edit it.
I've edited the model and put it back into VTF format, but how do I now put the VTF file back into the hl2_textures_dir VPK file?

You don't need to do this.

Just put it into any addon. ( With proper file structure )
