Deleting animations of a model

Hi, i have around 40 models in my map, and the total weight of the map is actualy 6mb, and i know thats way too much, i already been squishing and reducing blp's size but i didn't save enough space, i was wondering if theres a way to eliminate animation in a model, every model has at least 3 or 4 animations that are never used, i think this would take around 2mb, if this is posible, how can i do it?

Thanks!

There is this program, I don't know how well it works but the name looks promising.

Who did that program by the way?

Oinkerwinkle, I think.
