Hello,

Every time any Excel file is opened, I'd like Excel to automatically
check the size of the file being opened and if it is greater than say,
5mb, I'd like Manual calculate to be turned on. Is there a way to do
this?

The workbook_open event etc. wouldn't work since then I would have to
include this macro in every single Excel workbook I ever create or that
already exists. Having the macro in the xlstart folder etc. doesn't
work either since the macro there doesn't seem to be run before the
file is opened.

Is there a way to do this using VBA? or VB6? or at the command line?

Thanks,
