Hi Daniel

So, if you change the default File location to an empty folder, close Excel,
then open Excel again, are you saying that it still shows those files when
you go to FileOpen?

Sorry, but yes. These are shadow files, one has no extension, but they
are, yes, in the list. They are, too when I install XL2007 after
XL2003. XL2007 grab them back in its own dropdown list !
