i figured out that it is possible to drag the skins one by one over.
Made it atleast easier
I know one, it is called Skincraft, it can be found on newsgrounds. If your skin is 64x32 (Skin format from the 1st version up to 1.7.10) it will say if you want to convert it to 64x64 (Skin Format for 1.8.X and above).
