Missing files

Since i use a tool to view the war3.mpq files, i posted here. It seems that a few of my .blp files have gone missing. I don't look at them too often, but i was gonna make a more natural knight skin (not all fancy) and it didnt seem to be there. Ive never looked for it before, but a few of the files that dissapeared seem to be getting edited by ppl on this site. Some are the footman, demon hunter, and the knight. I have no idea whats going on, but half of the units are missing their .blp files. This sucks, since ive been trying to get better at skinning, and re-skinning the gryphon rider over and over gets boring. Maybe someone knows something about this. If you do, then plz tell me.

same issue... is riderless horse an edited knight model or it have its own model and skin?
I'm unable to find it anyway, even if I look to the path found in editor...emote_confused

Missing textures for units ?!?!?
not all units have their textures in the same folder as their models
you ll find all the "missing textures" directly in the Textures\ folder.
