(Visual Basic 6.0) List all Folders

Demonstrates how to retrieve a list of all folders.

Note: Let's say we have a directory tree with the following folders in Google Drive:

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

This would be our result. Notice that the "name" of each folder is NOT the full path, but just the final folder name. To distinguish between the two FolderA's, we would need to get the parent information for each.
