What has it to do with running your program with several file names as
arguments? Is it two different ways to select several files in your
application? Or do you want one or the other?

This is unrelated to your question, but why do you use a global variable
in a class? Can't you use an instance attribute, or a class attribute? And
BTW, file is the name of a built-in, so using it to name a variable is a
bad idea.

So is it a third way of selecting multiple files? Anyway, if you want to
be able to select multiple files via askopenfilename, use
askopenfilename(..., multiple=1). The value returned by the function will
then be a sequence of file names.

Unrelated to your question again, but explicitely testing the type of a
variable is usually a bad idea. What can be stored in file? I'd set it to
None in the beginning, then test "if file is not None:" instead of testing
its type.

This line will always print None (or an empty string maybe), as
tkMessageBox.showinfo doesn't return anything. No print is needed here, as
showinfo already displays the message in a dialog.
You also have a branch of the 'if' explicitely returning something (the
result of the os.system call) and the other one not returning anything,
i.e implicitely returning None. Is there a reason for that? This is -
again - usually a bad idea as it makes your code difficult to understand.
