Save files into specified directory in Qt

Question

I'm trying to save a stringlist of files into a specified directory. All I found was saveFileDialog where I save only one file at a time. Is there any other way to save multiple files into the target folder?

Answer 1

The QFileDialog ist for a user to choose a location for saving, not the actual saving process. How you save a list of files depends on what exactly you have, if you mean a QStringList of file locations you simply want to copy the easiest way would be something like this:

QStringList input_file_locations;
QString output_file_location = QFileDialog::getSaveFileName(...);
for (int i = 0; i < input_file_locations.size(); i++)
{
    QFile::copy(input_file_locations.at(i), output_file_location + QString::number(i));
}

(I did non add the extraction and preservation of the actual file name to keep the example as simple as possible)
