You have solved my problem, thank you very much.

It's caused by window|new window and it's just another view into the same
workbook (not two separate workbooks).

Select the window you don't want.
hit ctrl-w
save the workbook (or you'll have to do it again)

I found that when I open an Excel file, the file will automatically open in
duplicate. One of them in the name of [ABC.xls:1] and the other [ABC.xls:2].
The contents in both files are the same. I wonder what has happened?
