Thank you for your welcome and your feedback.
Here's a clearer explanation:
I have a photo folder for my work. Inside, it's sorted by year. And I put photos according to events.
So I want to create a new folder called event 1, for example, and then use alfred to automatically create 5 empty folders in it:
Here is the aborescence
Photos > 2024 > Event 1 > Légères (folder 1) - Lourdes (folder 2) - Palmarès (folder 3) - Photos (folder 4) - Sélection (folder 5).
And ideally, if I can, in light, have a sub-tree with (PNG) and (WebP), that would be absolutely perfect.
I'm going to have a look while I wait for the other post you mention.
Thanks
