I'm running Python 2.6.2 on Windows.  I'm passing filenames to the
batch files and I need all filenames to be processed.  I can't have
any fails.  I'm working on logging any fails I do have so that I can
maybe batch process at the end of the day.

This sounds like a good option, but I'm not totally sure on how to go
about this?

I had the same idea, but I believe it would involve having another
python script run all day long, which wouldn't necessarily be a bad
thing, but I'd like to explore other options as well.

The batch file is moving large video files.  Duration probably ranges
from 10 sec to 45 mins.  On average, the application takes longer to
process the files than it does the batch file/python script takes to
copy them, but I'm concerned about the occasional time that the
application finishes a small file right after finishing a large file.

Thanks for your response!
