Flash projector

Hi!
I have a trouble with FSCommand and I haven’t found a solution in the archives.
I have a movie that opens some files .avi in the projector. The .avi are in the folfder “fscommand” and I open them with the
fscommand(“exec”,“filename.exe”).
I should close the opened projector when I open another one, or the .avi in the same projector.
Is it possible?
I tried to use the fscommand “quit”, but it closes everything, obviously!
Sorry for my english.
Thanks in advance for your help.
