Is there a way to force export to use "frames to files" WHEN USED IN A
BATCH PROCESS?

I need to create a command or batch script to export "frames to
files," for a large number of files, but can't seem to find a way.
When I create a batch process using "export" as my "option", and "use
settings for each file", the batch process only exports the FIRST
FRAME, instead of "frames to files" --even if the file was most
recently exported and saved using the "frames to files" option.] Is
there another way to force the export option to use "frames to files"
when involved in a batch export process?

Is it necessary to write a script for this -- and if so, I'm not sure
how to properly use the exportFileStyle property (="Frames to Files")
and exportFrames function properly.

Any help would be greatly appreciated!

Thanks, Dave
