opening an excel file opens a duplicate file of the same file

i have an excel file that when i open it it opens another duplicate file of
the same name with a (2) at the end of it.. if i edit one it updates the
second.. how can i tell it to not open another duplicate file?

It's actually opening a second window into the single workbook.

Select the window you don't want to see and hit ctrl-w.

Then save the workbook (or you'll be doing it again when you reopen the
workbook).
