It probably has nothing to do with the file size. Perhaps a corrupt XL2003
installation. Are you able to open any file at all in your 2003 version?
Check also the contents of the XL2002 version, any special add-ins it might
be using, etc.

Provide more information on why you think the problem is related to the file
size. What error messages do you get from XL2003? Perhaps others would see
the problem when you post more information.

Under Office 2000, all files exceeding 12 MB are opened without any problems.
After upgrading it to Office 2003/Excel 2003, similar files can't be opened
normally. However, even if I can, all the formulae and formats are lost
which cannot be recovered any longer. Is there any settings I should do
before the files can be retrieved again?
