    You need to post a larger section of the code where the problem is.
    Also a larger stretch of the error messages are helpful.

    What is the OS and compiler you are using?

    @koahnig I am using ubuntu I have already posted the code to upload file on server and for select the single file my code is void

      void MainWindow::selectFileDownload()
     {
    
         QString downloadlocation = QFileDialog::getOpenFileName();
        QDir dir = QFileInfo(downloadlocation).absoluteDir();
        qDebug() << dir;
        qDebug() << downloadlocation;
         this->downloadLine->setText(downloadlocation);

      @developerNancy There is no such constructor. Please check the documentation: http://doc.qt.io/qt-5.8/qdiriterator.html

          Using this code
          QDirIterator UploadFolderFiles(UploadFolder, QDirIterator::Subdirectories );
          while (UploadFolderFiles.hasNext()) {
          qDebug() << UploadFolderFiles.next();
          }

          My output is this:
          /Desktop/testingQT"
          /Desktop/testingQT/Linuxapp"
          /Desktop/testingQT/.."
          /Desktop/testingQT/."
          /Desktop/testingQT/dfgdggd"

          But I want only files.

                          If you only want the files within a folder just apply the correct QDir::Filters to the QDirIterator.
                          Just a guess: QDir::Files as can be found in http://doc.qt.io/qt-5/qdir.html#Filter-enum

                          --EDIT

                          QDir::NoDotAndDotDot is not neccessary if you use QDir::Files as . and .. are folders and not files. my bad, sorry

                            @developerNancy Would be great if you could provide me with some working example of this.

                            Thanks

                                Just use QDirIterator::QDirIterator(const QString &path, QDir::Filters filters, IteratorFlags flags = NoIteratorFlags) instead of QDirIterator::QDirIterator(const QDir &dir, IteratorFlags flags = NoIteratorFlags) as your constructor and apply the filters you need as listed in QDir::Filters

                                    So in short, it is like first shown

                                    QDirIterator it(dir, QStringList() << "*.*", QDir::Files, QDirIterator::Subdirectories);
                                    

                                    The

                                    QStringList() << "*.*"
                                    

                                    tell what files you are after.

                                    If you dont tell it, it seems to think u say "i dont want any files" which makes sense.

                                      So in short, it is like first shown

                                      QDirIterator it(dir, QStringList() << "*.*", QDir::Files, QDirIterator::Subdirectories);
                                      

                                      The

                                      QStringList() << "*.*"
                                      

                                      tell what files you are after.

                                      If you dont tell it, it seems to think u say "i dont want any files" which makes sense.

                                      With the difference that *.* does only match files that contain a dot but misses all files without file extension ;)

                                          Not 100% sure if it matches all files but should do with all visible files.
