The file format in Excel 2007 differs from that in the earlier versions. If
you open an existing XLS file made with Excel 2003 (or earlier) then Excel
2007 automatically switches to compatibility mode so enable it to open the
older format. A newly made Excel 2007 file will generally have the extension
XLSX. Such a file will open in native (non-compatibility) mode.

I recently installed Excel 2007 and notice that many of my files are
running
in Compatibility Mode. What does this mean and how do I stop it from
doing
that (if I even want to)?
