Here's a useful tip that came from the G Suite Google+ page. If you choose to do so, you can disable the options to download, print and copy files from your Google Drive for commenters and viewers.
This feature provides content owners with more control over the distribution of their work. For example, you may be working on something that will eventually be released publicly, but you certainly don't want your draft material to accidentally be made available to anyone.
Fear not, in G Suite, you can change your Sharing Settings to lock down your work. Find the "Disable options to download, print, and copy for commenters and viewers," option and you can rest easy that you know where your content is going.
