Hi Andrew:
It was a single "combine". I'll ask AIM Services if 10 combines is 10 times as long or much the same duration. Depends on how they wrote it I guess.
As a short-term solution, we'll copy to a local drive until their infrastructure is upgraded. However it feels like a work-around and could lead to problems. I'm OK with a scenario where a local copy of data is used for reporting purposes. But running the number changer locally and then copying back to the LAN once or twice per week is inviting problems (overwriting files, copy errors etc.).
I'll post results here.
