Cloud Data (File) Storage Servers

Google Drive

To directly download a raw file from Google Drive use the URL:
https://drive.google.com/uc?export=download&id=
followed by the ID of the file. So we can find the ID of files by opening the file in Google Drive, but that defeats the point of having a direct download doesn't it?

https://developers.google.com/drive/v3/reference/files/list
shows us how to get a list of files. And we can apply that to a single request via:
https://www.googleapis.com/drive/v3/files?q=<query>&key=<authorization token>
but:

1. we need an authorization token to access the users drive. Basically this tells google who's drive to access. So the user has to figure out how to provide that. At this point, it's not terribly difficult,

"Go to Google Console:
https://console.developers.google.com/
In left menu select 'Credentials'. Click 'Create credentials' and select API key. Click 'Browser key' Copy the generate key."

2. We need the ID of the folder (which we then have to find under the /main/ folder, which has ID 'root' to ensure we are looking there and not finding a folder of the same name under a sub folder). To find a specific folder called "Public" in the main folder, q is (html encoded):
name='Public' and 'root' in parents
Note that the "in parents" part means that the file we are looking for has a parent with that ID. e.g.
https://www.googleapis.com/drive/v3/files?q=name%3D'Public'+and+'root'+in+parents&key={YOUR_API_KEY}
To find things in a specific folder, given the ID of the folder:
name='test.TXT' and '0B0ap0WDOII5mbjdwajNBMlRoZUU' in parents
e.g.
https://www.googleapis.com/drive/v3/files?q=name%3D'test.TXT'+and+'0B0ap0WDOII5mbjdwajNBMlRoZUU'+in+parents&key={YOUR_API_KEY}

Except... That doesn't work:
