How to sort file path names in hierarchy basis?

Question

I want to sort out file names in hierarchy basis.

Let say I have below list of folders:

D:Movies\Hollywood\Comedy\adultcomedy
D:Movies\Hollywood\Comedy\horrorcomedy
D:Movies\Hollywood\Romantic\ adult
D:Movies\Bollywood\Action\comedy
D:Movies\Bollywood
D:Movies\Hollywood\Comedy
D:Movies\Hollywood
D:Movies
D:Movies\Hollywood\Romantic

I want to sort them in single line, which means the last children should be sorted first, and grand grand parent should be sorted as last Child

(I.e):

1. Movies — Grand parent
2. Hollywood — child of Movies
3. Bollywood — child of movies / Sibiling of Hollywood
4. Comedy — child of hollywood / grand child of Movies
5. adultcomedy— child of Comedy / descendant for Movies
6. horrorcomedy — child of Comedy /sibiling of adultcomedy
7. Romantic — child of Hollywood / Sibiling of Comedy and same for others

Here by I wanted to sort this as descendant from grand parent.
(i.e) —> 4 th level is extreme grand child in this structure, which means it should sort:

• As first element adultcomedy
• then it’s sibiling horrorcomedy
• then 4th Level of grand children adult from Romantic
• then comedy from Action
• then Comedy which is child of Hollywood and parent of adultcomedy,horrorcomedy and
• then Romantic
• then Hollywood
• then Bollywood
• finally Movies.

D:Movies\Hollywood\Comedy\adultcomedy D:Movies\Hollywood\Comedy\horrorcomedy D:Movies\Hollywood\Romantic\ adult
D:Movies\Bollywood\Action\comedy D:Movies\Hollywood\Comedy D:Movies\Hollywood\Romantic D:Movies\Hollywood D:Movies\Bollywood
D:Movies 

Here I can’t use array,. Only I can use tree strucutre to solve this problem.,

What I have tried.,

• tried to count length but it’s failed due to dynamic path change
• checked whether another path has substring of another path

But none of the algorithms are working.

Sample code to understand the structure:

<forall _="ChildrenWithKey" name="fDir" in="vtList" param="ElementDir" >
 <!-- here vtList has element paths as children &  all the path has a Key:ElementDir name- alias name, so that we can use this tree anywhere -->

<!-- lets consider the list of paths above mentioned all has a Key:ElementDir -->
