Would that work when using subsets of frames?

And thinking out loud:
What is the first frame?
Is it Frame_0, Frame_1 or the first frame actually rendered in the 
directory with the same base name?

Would you have a flag to switch it on and off for when we wanted to 
overwrite files?

Sorry for sounding negative but I don't think this is trivial.
On the positive side. You could pop up a warning asking if the user 
wanted to overwrite with an option to pick Yes/No/All (for animations)
