 <p>I'm just messing around with the Gdriv.es service and the link you posted. Thanks for sending me down the rabbit-hole... </p> <p>Google Drive folders seem to either have 28 or 72 character long ids. Most of your product subfolders have the 28 character id format. Interestingly, there are some other folders that show up in your posted link that don't if you go in a different way to the same folder <a href="https://drive.google.com/drive/folders/0ByX-7AGzNtLkfnJDcC0tRm5xcE9aYlp3akljS3p4OWxpeDNId0FlaEdONFVTak0xeld4NGc" rel="nofollow">https://drive.google.com/drive/folders/0ByX-7AGzNtLkfnJDcC0tRm5xcE9aYlp3akljS3p4OWxpeDNId0FlaEdONFVTak0xeld4NGc</a></p> <p>Going through my own drive, what I'm seeing is that all of the older folders I have from 2009 and earlier have the 72 character id format. Folders from 2012 are 28 character ids. Unfortunately, I don't have anything in mine between summer 2009 and 2012.</p> <p>A quick twitter search shows a <a href="https://twitter.com/vivekhaldar/status/275090459867635713" rel="nofollow">Dec 2012 tweet</a> that kind of looks like an announcement.</p> <p>My guess is there was some sort of API change with Google Drive from the 72 to the 28 character ids before then, and Gdriv.es doesn't support the old format. Maybe if your root folder was created before that change, you could create a new root folder and shift your content over?</p>
