FOSS gamedev and creative worlds

Hey,

Could someone please tell me how to install a texture pack on 0.4.
I've tried everything and I'm just confused as to where to put it.

If someone could just explain the following in simple terms like:

Folder > data > mods > extract here ...etc

Also when new updates are out is it possible to keep the old world I had and transfer it over instead of starting again ?

data > mods > default > textures is where you're looking for.

However I suggest you move the textures folder, or rename it just in case. Then your texture pack, just rename the fold to "textures".

Don't forget to clear your cache folder:)
