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.
