Who is asking?

So, you've detected that I am simultaneously accessing a file with more than one application. You've detected that the file has been "changed by another application". I appreciate being asked if I want to reload the file after it has been changed in another application. However, I have one question.

Which application are you? You've failed to identify who you are. Perhaps you have the version of the file that I want to keep. If you are going to ask me if you should reload a file (and potentially lose any changes you may have in memory), please identify yourself.
