Are your users filling up your CIFS fileserver with MP3 files? Sick of sending out emails outlining IT policies, asking for their removal? However your manage it now, the best way to avoid the problem in the first place is to set up filtering on your CIFS server file shares.
So, to use the same example, lets say you don’t want your users to store MP3 files on your \\PRODFILES\Public share.
1. Navigate to the \\PRODFILES\C$ administrative share.
2. Open the folder in the root directory called .filefilter
3. Create an empty text file called mp3@public in the .filefilter folder.
4. Change the windows security on the file to restrict access to certain active directory groups or individuals.
That’s it! Once the file is created and security is set, users who are restricted by the file security will no longer be able to copy MP3 files to the public share. Note that this will not remove any existsing MP3 files from the share, it will only prevent new ones from being copied.
