I recommend leaving 2000 installed and install 2007 in a NEW
Directory(folder). The files will be available to both. To get full
functionality of 2007 you will need to save your .xls files as .xlsx (non
macro) or .xlsm (macro). Be advised that Outlook 2007 WILL take over.

When I install MS Office Professional 2007, will it automatically move my
excel and word 2000 files into the new program? I assume it will
overwrite
my 2000 program even though the 2007 is a complete program and not just an
upgrade. Is that correct?
