Im trying to get a list of all folders and subfolders that I have in Zoho Docs

The main problem is that when I use the function Folder it only provides me the folders that are placed in root. If I want to get the subfolders of each folder I have to recall the /folders function again passing the ID of the folder that I want to get the subfolders as a parameter. 

This is so annoying. 

Is there any method where I can get all the folders and subfolders information in just one function call?

Thank you in advance.
