Double Click on an Excel File Open in a new Window Not in the same window as an excel spreadsheet that is already open

[Chrisdudley7]

How do I set an option so whenever I double click on an excel file it opens into a new window rather than the same window of an excel spreadsheet that I already have open. I get the purpose of having it open into the same window that is already open, it is so you can copy/move sheets, apply the same macro, etc. I want it to open like when you open a word document, where if you already have a word document open and double click on another word document to open it opens separately. I have researched this in the past, and there was not an option built into Excel. I just got Excel 2013 and hope that by the year 2013, Microsoft figured out a feature that annoys the casual excel user.

The workaround is that I have to open a new blank excel file, close it, then drag and drop the new excel file I want to open into the second empty window. It gets really tedious to do this all day. I seldom work within the same workbook or window and often have different, unrelated excel spreadsheets open at any given time.
