3DsMax file name problem

hey folks,
i have a short question about 3DsMax Script.

my problem:
i am rendering a batch-render job (6 views .. each view a new camara and range = frame 0 to frame 0)

as i save the file (my given file name e.g. = my_render.tga) @ view 1 is saved as "my_render0000.tga"

so the number at the end of the filename is added by max.

i need to know how to stop 3DsMax to add this number.
