Nested Folders selection

I'm working on a selection in which I have a list of folders. This is the structure:

Let's say I want to select a folder. The folder, its children, and future children will be selected.

First Question: What if I'd want to select a folder but not the children folders (i.e. I want to select just the files contained in the turkey folder but not the children folders)? Would I have to select the folder, enter and deselect all the children folders?

Second Question: Would you use that state for the root to say that some of its children is selected? To me it's quite common

Thank you!!
