IMVSCSetFile

The IMVSCSetFile Interface from the MontiVision Smart Control  provides methods to change the file/folder for file source/sink filter and MV Batch File Source filter. The methods reconnect the filter graph to work with the new files. Therefore the filter graph must have the state:  STATE_STOP to change the files/folder.
