: differentiate the version from the file extension

Since arriving on the market of the 2007 version of Office came to light some change on the file format.

I suggest you learn how to differentiate the format of the version of Excel workbooks in which you just received is recorded.

How?

1. If not already done so, display the file extension in Windows Explorer.
• Explorer -> Tools -> Folder Options -> Display -> Advanced Settings -> uncheck "Hide extensions for files whose type is known."
2. If the extension is ". xls" is that the file was saved as 97-2003.
3. If the extension is ". xlsx" or ". Xlsm " means that the file was saved in 2007 which is the same as 2010.

To summarize:

1. 97-2003 => . Xls
2. 2007/2010 => . xlsx or . Xlsm
