I\'m playing around with QFtp (yes .. I know) and all works well.
Using code from their own example(s) as a guideline.

You can make the progress bar present the progress as a percentage:
void FtpWindow::updateDataTransferProgress(qint64 readBytes, qint64 totalBytes) { progressDialog->setMaximum(100); progressDialog->setValue((qint)((readBytes * 100) / totalBytes)); }
