How can you easily find block textures in a file folder?

I'm trying to edit some block textures, but I cant seem to find the correct one. each texture has some really long name like "e85904034", and there are hundreds of them. Is there an easier way to find the correct one without having to search the 100's of textures to find the right one??


Solution 1:

First go to %appdata%\.minecraft\versions\1.8.4 (or any other version number).
Then copy 1.8.4.jar and change the name to 1.8.4.zip (make sure file-extensions are visible).
Open the ZIP-file, and go to assets\minecraft\textures\blocks.

Here you'll find all block textures.
