Where do you find the default decal files in?

I wanna edit some but I can't find them in my Blockland folders. Can someone tell me where the files are?
Also, I put this topic in Coding Help because I'm not sure where to put it.

This would probably go into General Modification Help.

Anyway, you should find them in the Add-Ons folder, Decal_Default.zip
