Create Folder

See more Google Drive Examples

In the Drive API, a folder is essentially a file — one identified by the special folder MIME type application/vnd.google-apps.folder

See Google Drive Files: create for more details.

Also See Working with Folders for more details.

-- It requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- This example uses a previously obtained access token having permission for the

rest:add_header("Content-Type", "multipart/related")
