How to catagorize my files on my WD hd into folders so I can organize my movie files

I have made folders in on my WD hard drive but when I plug into the player, all 200+ movie files individually show up.

I bet I am missiing or overlooking  something pretty simple?? 

My hard drive is a 750gb passport  essentiall.


Ok, so after you plug in the drive, how are you then accessing the files?   What “Menu Path” are you taking? 

It WILL show you all files if you ASK for “All Video” or whatever.  It will disregard your folder structure if you do that.
