I want to store several files on Google Drive that later will need to be downloaded without authorization by some automated tool (for example filters for adblock so several different PCs can update from them). Is it possible to generate direct download link for file on Google Drive that would work without authorization?
If you want to link to a file at Google Docs for direct download you can use the following address scheme: https://docs.google.com/uc?export=download&id=YourIndividualID

You can actually set view/edit permissions to any e-mail address by clicking the
Share-button in the upper right but the persons who gets the permissions will have to create a new Google account or sign in with an existing Google account use the document.
Alternatively, you can set the document to be viewed and edited by anyone who has the link to the document (no sign-in required), email the link to the particular email address and request them to not share the link with anyone else.
