[SOLVED] Read unknown .txt files in a folder?

[MrNoway]

let's say there are some unknown .txt files in a folder,

how can I read them without knowing the file names?

is that possible, I googled already quite alot, but couldnt find anything

€ so how can I request the file names? If I know them I can also read them.

If you know the filepath for the folder where the files are stored you can get the individual file in the directory using "QDir":http://qt-project.org/doc/qt-4.8/qdir.html . Have a look at the "examples":http://qt-project.org/doc/qt-4.8/qdir.html#examples , its pretty much selfexplanatory.

To open the files you can use "QFile":http://qt-project.org/doc/qt-4.8/qfile.html .

cool thx,

luckily there was an already nice sample code

this could be helpful for someone, nice

@ QFile file2("movie-list.txt");
file2.open(QIODevice::WriteOnly | QIODevice::Text);
QTextStream out2(&file2);

 QDir dir("movies");
 dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
 dir.setSorting(QDir::Size | QDir::Reversed);
 QFileInfoList list = dir.entryInfoList();

 out2 << "     Bytes Filename" << endl;
 for (int i = 0; i < list.size(); ++i) {
     QFileInfo fileInfo = list.at(i);
      

    out2 << qPrintable(QString("%1 %2").arg(fileInfo.size(), 10)
                                             .arg(fileInfo.fileName())) << endl;
