Here's an example of how to list files in a directory from Qt Documentation (link):
#include <QDir>
#include <iostream>
int main(int argc, char *argv[])
{
dir.
setFilter(QDir::Files |
QDir::Hidden |
QDir::NoSymLinks);
dir.
setSorting(QDir::Size |
QDir::Reversed);
QFileInfoList list = dir.entryInfoList();
std::cout << " Bytes Filename" << std::endl;
for (int i = 0; i < list.size(); ++i) {
std
::cout << qPrintable
(QString("%1 %2").
arg(fileInfo.
size(),
10) .arg(fileInfo.fileName()));
std::cout << std::endl;
}
return 0;
}
#include <QDir>
#include <iostream>
int main(int argc, char *argv[])
{
QCoreApplication app(argc, argv);
QDir dir;
dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
dir.setSorting(QDir::Size | QDir::Reversed);
QFileInfoList list = dir.entryInfoList();
std::cout << " Bytes Filename" << std::endl;
for (int i = 0; i < list.size(); ++i) {
QFileInfo fileInfo = list.at(i);
std::cout << qPrintable(QString("%1 %2").arg(fileInfo.size(), 10)
.arg(fileInfo.fileName()));
std::cout << std::endl;
}
return 0;
}

Directories can be created with mkdir and to check if they exist use exists.
