Abstract
An apparatus and method are described for performing file coordination operations on a computer system. For example, one embodiment of a system for performing file coordination comprises: a file coordination service having arbitration logic for arbitrating among different read and write processes attempting to perform file read and write operations, respectively; and a file presenter representing a file opened by a file editing application and registering the opened file with the file coordination service; wherein prior to permitting a read/write process to perform its designated read/write operation, the file coordination service notifies the file presenter and waits for a response from the file presenter indicating that the read/write operation may proceed.
