Block media file like .mp3, .mp4, avi, mkv, .wma, .wav etc to copy into Network or domain

Hello, friends!you can just block all files extension in whole domain or network by just follow below process:

File Screening is one of my favorite features in FSRM. One of the biggest challenges in running a file server is keeping certain kinds of files off your file server. Typically those are things like mp3 (and other digital music) files, video files, and executables just to name a few. With File Screening, you can control what file types can be saved to folders on your file server. There are two types of File Screens: active and passive. Active screening blocks configured file types from being saved to the folder and sub-folders. Passive screening allows the configured file types to be saved, but performs actions like logging or email notifications and can be useful for monitoring.

Creating a File Screen

In the FSRM administrative tool, go to File Screening Management, File Screens, and click on Create New File Screen.

Create File Screen

Like Quota Management, Microsoft recommends using templates for setting up File Screens. In our example, we’ll block users from storing executable files in their home directories. Set the file screen path and choose a template. Click Create to create the file screen.

File screen path and template

Editing the File Screen Properties lets us go in and customize the file screen further. With this particular template, the Screening type has been set to Active meaning that users will not be able to copy any file classified as executable into this path. (Note: this applies to everyone… even users with Administrator rights. If you’re setting an Active file screen, be really sure that is what you want to do.)

File Screen Properties

The E-mail Message tab lets you set a customized message that can be sent to the user (and a server administrator if you desire) that is trying to copy the screened file to the file server. Like Quotas, I highly recommend translating this into something your end users will understand; the built-in messages don’t always make sense to end users.

I also recommend leaving the e-mail notifications enabled instead of relying on the built-in error messages that will be generated by Windows on their computers. End users will receive a very basic “Destination Folder Access Denied” error that will tell them “You need permission to perform this action.” If you’re a larger organization, your help desk or frontline support is going to think they’re dealing with a permissions problem unless you’ve provided them with adequate troubleshooting steps and documentation.

Exceptions

You’re always going to have those times where the rule that applies to everyone needs an exception. In those situations, File Screening has the ability to create

Destination Folder Access Denied

te exceptions for sub-folders. In the FSRM administrative tool, highlight the file screen you want to modify and then click Create File Screen Exception.

Create File Screen Exception

Choose your Exception path, choose the file group that should be excluded for this sub-folder, and then click OK. That’s it!

File Groups

The pre-defined File Groups that are built-in to FSRM are… lacking to say the least. In my earlier example, I blocked executable files from user folders on the file server. The problem is that this also blocked .ps1 (PowerShell scripts), .js (JavaScript), and .vbs (VB scripts) from user folders. Oops, huh? If you have any sysadmins or web developers using those folders, you’ve got a problem. Let’s take another file group: Audio and Video Files. First off, why are these together and not two separate groups? Second, there are several file types missing. The most glaring are .m4a and .m4v files that are used by iTunes. Oops again.

Pre-defined File Groups in FSRM

Needless to say, you’ll probably want to edit the existing File Groups or even create your own that fit your organization’s needs.
