GEODI handles files accessed via Dropbox, GoogleDrive, OneDrive, FTP or WebDAV as if they were local folders. When opening the file, it retrieves it from the source. Data sitting on cloud servers may take longer to process than you expect.
WebDAV is a generic file sharing method supported by some data sources. Many vendors, including Microsoft, support it. http://www.webdav.org/projects/ . You must use WebDav to connect to the Microsoft Sharepoint platform.
