Assuming your generator doesn't somehow delete or modify the file specifications as it yields them. It would be helpful to see the code for rootobs, if you have it.
Ahem. If Sayth is using the correct terminology and rootobs actually is a generator (not, say, a list or tuple), then no it won't work. Once a generator is exhausted, it's exhausted. Besides, the nested for-loops over the same iterable is a dead giveaway that something is wrong.
