Hi sarah, This is untested but should work:
QRegExp regExp("(m|c)_([0-9]{6}).rcp"); if(regExp.exactMatch(fileName)) { //Here we know that filename matches the pattern QString letter = regExp.cap(1); //Will be "m" or "c" QString number = regExp.cap(2); //Will contain the six digits as a string } Regular expressions are a vast topic, you will find a lot of documentation by googling it.
