Forgive me if this is commonly known (I am new). I simply want to know how I could set a different folder as the directory for saving existing carts and creating new ones as opposed to the files being saved right in the \pico-8\carts file. Say I wanted to save all of my projects in the folder \pico-8\carts\projects.

Please refer to this, @emalan-p, which explains how to change directories for your carts.

Thanks!
