Models that i download don't have textures

[mememan_64]

So i wanted to download the pokepark quagsire model and i succeeded but when i opened it in paint 3d (or any other 3d model viewing application) it won't show the textures, i have no idea why it does this so how can i fix this?

Advice : don't use Paint 3D.
They developed it only to make the Creators update somewhat new.
