Mass Assign Viewers to all files in File Library
One of the best apps you have is the File Library app. It allows us to upload and share files and even have rights to limit who can view/download the files.
The biggest problem with it is that if you assign viewers to just the page the app is on, anyone who googles and finds the link can still download the file, so you have to add viewers to every individual file as well to limit who can actually download the file. There should be a way to mass assign viewers to all files within a file library.
