Abstract
A file stream exchange system and method are provided. The system can be employed, for example, with a storage system that supports transactions as a primary mechanism and employs a rich type system. The system provides a mechanism for the storage system to provide reliable updates to file streams while preserving the common criteria for security. The system includes a replace stream component which is a kernel mode mechanism that allows transactional exchange of stream data of two file-backed items without violating the common criteria for security.
