I am just asking out of curiosity. It goes without saying that I am talking about files with the same name but different extensions. Either way it looks bad in this case. The question is whether in this case QAP could not hide these
underline characters. QAP must process it but not necessarily display it.
For comparison the view in Windows Explorer, as you can see Windows does not add superfluous characters to the end of the file name. Well, if you can't do it, so be it.
