No, but the error message you get when you try to open the file with
OPENR will tell you this. You may want to try out my open_file
procedure which adds a couple of additional features such as seemless
integration of the dialog_pickfile routine if you specify a name with
wildcards (or no name at all). And this does error checking...

You can find open_file.pro at
