What is a file screen exception in Windows 2003 R2 File Server Resource Manager (FSRM)?
June 11, 2006
A. In previous FAQs, I discussed using file screens to block a certain type of file (e.g., all audio and video). There might be times that you want to enable a certain file type, but only within a defined folder that allows granular control of where data can be placed. For example, if I had a file screen to block all audio and video (which includes the .mp3 file type), I could create a subfolder named MP3 and add an exception to all MP3 extensions in that folder. To do so, perform these steps:
Start the Microsoft Management Console (MMC) File System Resource Manager snap-in (Start, Programs, Administrative Tools, File Server Resource Manager).
Expand the File Screening Management branch and select File Screens.
Click Create File Screen Exception in the Actions pane
Click Browse and select the path to which the file screen exception should be applied. You can then select the template you want to derive the settings from or set specific values by clicking Create, which lets you specify file criteria for the new group type (e.g. *.mp3), as the figure shows.
Click OK.
The file screen detail will now show the exception, which takes precedence over blocks. For example, in the example that the figure shows, d:users has a screen on all audio and video; however, the exception on the subfolder MP3 will take precedence, allowing .mp3 files to be written to the MP3 subfolder despite the file screen on its parent folder.
