Takes two parameters, FolderPath, bRecursive
Description:
This command loads a list of sub-folders under the folder named in Source into the Work Query, with a single field named Folder.
If bRecursive is true (has any value), the ListFolders command will provide a recursive list (i.e. return all of the subfolders down any number of levels).
Example:
ListFolders "/Public/anyFolder", "" 'Provides single level folder list
ListFolders "/Public/anyFolder", "y" 'Provides recursive folder list
