File Server Resource Manager
The File Server Resource Manager (FSRM) API is used for many file and storage related management tasks, including setting a limit on the size of a given directory using directory quotas, restricting the type of data that can be stored under a given directory using file screens, and generating storage reports that administrators can use to analyze storage utilization. Most FSRM interfaces support remote as well as local server functionality.
The FSRM API is designed for use by C/C++ and Visual Basic programmers and those writing scripts. Familiarity with COM, file systems, and storage is required.
For conceptual information on FSRM, see Step-by-Step Guide for File Server Resource Manager in the Windows Server 2008 R2 Technical Library on Technet.
The FSRM API is available starting with Windows Server 2008. Note that the FSRM feature is not installed by default and must be added via Server Manager or related mechanisms. Starting with Windows Server 2012 and Windows 8 a subset of the FSRM APIs are available without installing the FSRM feature.
