Is creating a file-tree a built-in feature of q?

Question

I've seen in .Q sources (q.k) that applying a dir-symbol to empty symbol (or to its sub-dir symbol) creates a full folders-tree, try this:

`:dir1 `

Is this behavior documented somewhere? Or is this a feature for internal use only and is subject to change?

Answer 1

Its because we can use key/value to file-symbol I think all other stuff works. Applying to all (`), and to the specific key works as in usual dictionary.
