Hello!
I'm currently working on a system for loading and saving text files. My end goal is to have an exported binary for my Pico-8 program. This however introduces some limitations, as exported binaries can not import user-editable files from disk. It is however possible to load files that are dropped from a file explorer into the Pico-8 program. To make it easier for users, I want to open the OS file explorer from within Pico-8. Usually this can be done from the Pico-8 terminal by typing folder, however this command does not appear to work from within a cart.
I'm fairly certain this can be done, as the Picocad binary allows the opening of the file explorer.

Appreciate all answers/ suggestions!
