All checks were successful
continuous-integration/drone/push Build is passing
..as it's more universal, should we start/allow passing more complex paths than "./res-folder".. should e.g. "./res/subpath" be passed to the former func, it would error out more easily, as the subpath would likely be non-existent, akin to `mkdir <path>` vs `mkdir -p <path>`.
