I know this is going to sound like a naive newbie question and yes a did do
a google search but didn't come up with anything useful. Perhaps I was
using the wrong search terms.
On my PC at work I have several excel files. Let's say for example I have
an excel file that I have opened and am working on. There may be times when
I may need to refer to another excel file. However, when I open up the new
excel file the one currently opened will close before the new file will
open. As my header suggests, is there are way to open up a new file without
having the older one close? Sorry, I'm posting this from home so I have no
idea what version of Excel I have at work.

Thanks in advance.
