  (I'm not Derek, but...) Probably just TMTOWTDI. In
  any case, both approaches should be workable, no?

Is there a reason you are using a regular expression and not just using the QFileInfo and QDir classes? You could always do something like this:

QFileInfo file("/home/dirs/somefile.txt");
QString newFile = file.absoluteDir().absoluteFilePath("newstuff.abc");

This should give you the same result you are looking for.

Thanks,
Eric
