I would really like excel to open files in a new instance of excel by default. Currently the only way I can do this is by starting excel and then File->Open. While this is only a little bit of extra effort, I've recently gotten in the habit of opening and closing 100s csv files daily and the wasted time really adds up. I've read several threads here, but mostly found people trying to accomplish the opposite of what I am. Thank you for any help.
