Sorry, this is a repost, as I posted it in the wrong group...any help
would be appreciated!

I am getting the following message when I try to open up a .txt file
that I renamed (using ren in command window) to a .xls file:

"The file you are trying to open, 'file1.xls', is in a different
format than specified by the file extension. 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?"


I do not get this message when I open it with Excel 2002, but I do
when I open it in Excel 2007. Is there any way to allow Excel 2007
to
allow me to open the file without prompting me every time? Is there
a
way to disable this? Thanks!!!
