Path Directories

I was wondering if anyone can help me with this.

I need to return the sub directory paths of a supplied path in a grasshopper friendly (tree structure) as shown below, while also returning also empty folders.

Main Folder1/item1.txt{0}

Main Folder1/Sub folder1/item1.txt {0;0}

Main Folder1/Sub folder2/item1.txt {0;1}

Main Folder1/Sub folder3/=Empty={0;2}

Main Folder2/Sub folder2/item1.txt {1;1}

Main Folder1/Sub folder2/SubSub folder 1/item1.txt {0;1;0}

Similarly I wish to output the file directory at the tree address it lies in.

so in the first and last instance I would like for them to have this structure in the output;

{0}(i=0) contents = Main Folder1/item1.txt

{0;1;0}(i=0) contents = Main Folder1/Sub folder2/SubSub folder 1/item1.txt 

Any Idea how to do this recursively for all the sub directories within the supplied directory.
