Texturing leaves

Hi everyone interested in leaves. So I bought this beautiful tree and has a emmense number of leaves. I bought a FBX model. I imported the model as materials so I now have a number of random materials in the collection tab. so when I’m in the shading editor I have no idea what the file names align too inside the mapping folder I was supplied.
Has anyone out there acheived this mind boggling exercise. Is there an easy way to connect with the correct texture because it has some magic link?
