Hi bolsoi,

Simple: make sure the extension matches the file format.

Hello,
I'm trying to open SAP exported .xls file in the Office 2007 Excel, but I
receive warning notification "The file you are trying to open, "test.xls", is
in a different format than specified by the fil eextension. Verify that the
file is not corrupted and is from a trusted source before opening the file.
Do you want to open the file now?"
How to suppress this window?
thank you
