(Tcl) Lookup Google Drive Folder ID Given a Folder Path

Demonstrates how to find the Google Drive folder ID given a Folder Path.

This example demonstrates that we cannot simply query by folder name. (We can if every folder name is unique, but if not...) For example, imagine we have the following directory structure on Google Drive:

/AAWorkArea
/AAWorkArea/FolderA
/AAWorkArea/FolderB
/Folder2
/Folder2/FolderA

There are two directories named "FolderA". One is contained within AAWorkArea, and one is contained within "Folder2". To say it differently: One has the parent "AAWorkArea" and the other's parent is "Folder2".

To find the id of "/AAWorkArea/FolderA", we need to first find the id for "AAWorkArea", and then find the id for the folder with name="FolderA" and with AAWorkArea's id in FolderA's parents.
