Pretty self-explanatory title. I've been wondering for awhile weather or not to combine the Metal Sonic and Neo Metal Sonic folders together. They are the same character after all, just with different designs.
I think maybe not, I sometimes only images I searched about Neo Metal Sonic. In addition, Metal Sonic folder is already very large. - Pienso que mejor no, yo a veces he buscado imágenes únicamente de Neo Metal Sonic. Además, la carpeta de Metal Sonic ya es, muy grande.
I'd say combine them - like you said, they are the same character. Of course, I check out new pictures by way of DeviantWatch and I don't usually go back to look at old pictures, so it doesn't really make a difference to me.
