Thanks for the suggestions guys. The pre-filtered list is possibly one I can use.

Even with filtering ListFile will iterate through a lot of files.

You may have some luck with adjusting the max runtime of the processor but without checking the the processors implementation I couldn't know for certain if that would have any effect.

What's the best way I can do that? ListFiles is taking way too long and seems to try to dump the entire list to the flow when I test it on a smaller folder list. It would be good if the listing emitted files in smaller chunks so that the flow can start working on them. Regards, Jeremy
