when the QFile object is already constructed, querying whether the file exists is actually cheap, so do it right away instead of later on demand. that makes the calling code a bit cleaner. fwiw, that we need to explicitly query the file's existence at all is a result of QFile's completely useless error "codes" (which merely say which function failed, as if the caller would not know).
