I have a file server without any kind of file screen to prevent users from saving certain types of files in their folders. Our management changed and now I have to apply file screens to block some file types like pictures, audio, etc on most of the folders, with some exceptions.
The thing is most of the users folders already have all those kind of files saved inside it.
Is there a problem setting the file screens with those files already in there? My idea is to prevent new users to save more files in there and then manage like move or delete the old files.
Is it viable?
