If you've got the workbooks open in the same Excel session, you can use
Windows Arrange... from the menu bar.

I am attempting to open up multiple workbooks and seem to be unable to
display both workbooks on my monitor at once. When I open the second
workbook it just takes the place of the first w/o allowing me to display both
at the same time. Have tried to use the taskbar to "display windows
vertically (or horizontally)". Is there an Excel or Windows setting I might
be able to modify? Thank you in advance for your cooperation.
