Cypher - loading results while optionally adding count of relationships - neo4j

Question

I'm using a graph database to establish a relationship between folders, their children and users (be it owners or sharers of the folder).
Here is an example of my structure. Where orange are folders and blue are users. -
What I want my query to achieve: It should return direct children of the folder under query, and while doing so determine if the child folder being returned is being shared.
My query
MATCH (:Folder { name: 'Nick Hamill' })-[:CHILD]->(children:Folder)
WITH children
OPTIONAL MATCH path = (children)<-[*]-(:User)
UNWIND RELATIONSHIPS(path) AS r WITH children, r
WHERE TYPE(r) = 'SHARES'
RETURN children AS model, COUNT(r) > 0 AS shared
So the query works brilliantly (perhaps a little optimisation needed?) when there is a related user (see below), however, the query fails to return any result if there is no user relationship. I personally can't see why this is because it's an optional match, and surely the count could just return empty?

The query should be relatively self-explanatory but for the sake of clarity here's some expected outputs -
| Query Folder | Returned Folder | Shared? |
|----------------------|------------------|---------|
| Miss Dessie Oritz II | Nick Hamill | TRUE |
| Nick Hamill | Dr Denis Abshire | TRUE |
| Samara Russell | Shemar Huels PhD | FALSE |
| Shemar Huels PhD | Hazle Ward | FALSE |
I'm running neo4j 3.5.11 community edition. I feel like this should be a fairly easy solution, I'm just meeting the limits of my extremely limited cypher knowledge.
Appreciate any help!

I don't undertsand why you are using this in your query :
OPTIONAL MATCH path = (children)<-[*]-(:User)
UNWIND RELATIONSHIPS(path) AS r WITH children, r
WHERE TYPE(r) = 'SHARES'
With (children)<-[*]-(:User) you are searching all the path (without restriction on its size) between the children & User nodes.
And with the WHERE TYPE(r) = 'SHARES' you only want the SHARES relationship ...
So your query will work on this kind of pattern : (children)<-[:CHILD]-(:Folder)<-[:CHILD]-(:Folder)<-[:SHARES]-(:User)
Is it what you want ?
If so, can you try this query :
MATCH (:Folder { name: 'Nick Hamill' })-[:CHILD]->(children:Folder)
RETURN children AS model, size((children)<-[:CHILD*0..]-(:Folder)<-[:SHARES]-(:User)) > 0 AS shared
