File Screens are used to filter certain types of files from saving on your storage drive. It is not uncommon to see users saving huge pst or MP3 files on a shared storage which they are not suppose to do. File screens are used to block users from saving specific types of files as well as generate notifications when anyone attempts to save a blocked file resource on the server. File screens can be created for entire volume or specific folders. Lets quickly walk through the predefined file screen templates provided in server 2012 and steps to enforce it.
Launch Server Manager and browse to the File Screen Templates node. Those are the predefined templates
Right click Block Email Files templates, and select “Create File Screen from Template” option
Enter the volume name or the folder path (in this case its “Documents” folder) you want to screen in the “File Screen Path” text box
Click Create. Go to File Screen Option and Edit the file screen properties you just created.
You can select Active Screening to block users or Passive Screening to allow users and monitor the activity. Select all the file groups that you want to block. You can also edit the file groups if needed.
