How do I check for an existing folder in qml?

Question

I am programming in qml for a mobile client. I want to check if a particular folder exists on the mobile device. If not, I want to create it. I am using qml, so solutions can be in qml or JavaScript.

(Note: when I say "JavaScript", people say "use php,ajax etc." but I can only use JavaScript and qml on my mobile platform)

Answer 1

Do it in Qt (like @Stu-Mackellar already said).

Access Qt methods like this:

and do the Qt part like described here:
