The other day a customer wanted to classify his documents using the File Resource Manager of Windows Server 2008 R2. He needed to classify a huge amount of files with dynamic values in a short amount of time. He found that opening the files programmatically, one by one, writing their classification properties and closing the file again was pretty slow. ("Between 2 and 6 seconds per file" slow.)
The recommended and faster way is to implement your own classification module. In the following mini-series I will explain how to do this.
I hope this tutorial proves to be useful to you!
