decompress can be made similarly. Qt compression cannot handle folders, you have to manage this.

  1. /* compress files */
  2.     QFile inFile("test.txt");
  3.     inFile.open(QIODevice::ReadOnly);
  4.     QByteArray ba = inFile.readAll();
  5.  
  6.      QFile file("test.gz");
  7.      file.open(QIODevice::WriteOnly);
  8.      QDataStream out(&file);
  9.      out << qCompress(ba);
