well, There is really nothing wrong to leave those 100s of files in 2003 formats. But if you really want to change them to 2007, here is how.
You open the master file which links many other files into it, you do a "global" replacement of ".xls" to ".xlsx" (quotes are used here only for illustration).

Excel will find each link in your current file and change the linked file name to .xlsx. It will then go to the directory to check if the .xlsx file is there. So this will give you an opportunity to create the .xlsx version for that linked file.


Be careful with the global replacement. You do not want to, by accident, convert .xlsx to .xlsxx. Back up all your files before try this.
