I have some data on Google Drive, organized in folders, which I want to propagate on other servers. I have some script for propagating, but I need to download data from google drive. Is there a method for downloading folders via Google Drive API, that is also maintaining whole folder structure?
Folders are also files on Google Drive. The only difference is the Mime type. with folders its mimeType = 'application/vnd.google-apps.folder'.
There is no single method that will allow you to download everything with in a folder. Your going to have to do a file.list searching for the files with the parent Id to the file Id of your parent folder using search parameters (TIP: ''1234567' in parents'). This will return a list of the files contained within your folder. Then download each one.
Update from comment you need to loop though each directory or just do a main list of everything on your drive account and process the data locally.
File 1 (folder)
----> File 2 (folder )
--------> File 3 (actually a file)
---->File Four (actually a file)
'File 1' in parents
returns everything within the file 1 directory. If the mime type of the item returned is a directory (mimeType = 'application/vnd.google-apps.folder') make a request to get its contences
'File 2' in parents
returns everything within the file 2 directory.
