Preventing viewers from downloading a Google Drive file has been a highly requested feature for a long time now. We are happy to report: The wait is finally over. Not only can you disable all downloading and printing options for viewers of your file, but you can even prevent them from making a copy.
Copying a document or even just copy and pasting the text from within a document used to be the biggest loophole when downloading or printing was being blocked, but that workaround is no more! Of course, there will always be a way around features like this. It is still possible to take a picture of a document and then print or share that picture. But even so, this is a big leap forward in Drive security!
