    if( currentServerDir[ fileName ] )
    {
        QMessageBox::information(this, tr("Client FTP"), tr("Vous devez selectionner un fichier source\n %1 est un dossier") .arg(fileName));
        return;
    }    
 
    QDirModel *dirMod = (QDirModel *)(localDir->model());
    bool selectedIsDir = dirMod->fileInfo( localDir->currentIndex() ).isDir();
    QString path = dirMod->fileInfo( localDir->currentIndex() ).absoluteFilePath();
 
    if(selectedIsDir)
    {
        QFile *file = new QFile(path + "/" + fileName);
 
 
        if ( QFile::exists(path + "/" + fileName) )
        {
            QMessageBox  msgBox(QMessageBox::Warning, "FTP Erreur", "Le fichier " + fileName + " existe deja\nVoulez vous le remplacer ?", QMessageBox::Yes | QMessageBox::No, this);
            switch ( msgBox.exec() ) 
            {

The dir model shows its size as 0 or its also empty on the disk? Have you tried checking QFtp::error() and/or QFtp::errorString()?

thanks

in the dir model the size of files isn't 0, but dont have the real size, it have size less than the real size (for example: real size : 79 KB, size in dir model 64KB)

QFtp::error() return 0 .

I try to do just

void myMainWindow::cmdFinishedSlot(int cmd, bool error)
{
    toParentServer->setEnabled(true);
    toRootServer->setEnabled(true);
    refreshServer->setEnabled(true);
    newDirServer->setEnabled(true);
    deleteDirFile->setEnabled(true);
    renameFile->setEnabled(true);
 
    downFile->setEnabled(true);
    upFile->setEnabled(true);
 
    stopAction->setEnabled(false);
 
    setCursor(Qt::ArrowCursor);
}

void myMainWindow::cmdFinishedSlot(int cmd, bool error)
{
    toParentServer->setEnabled(true);
    toRootServer->setEnabled(true);
    refreshServer->setEnabled(true);
    newDirServer->setEnabled(true);
    deleteDirFile->setEnabled(true);
    renameFile->setEnabled(true);

    downFile->setEnabled(true);
    upFile->setEnabled(true);

    stopAction->setEnabled(false);

I delete the QFile* in

if ( ftp->currentCommand() == QFtp::Get || ftp->currentCommand() == QFtp::Put )

if ( ftp->currentCommand() == QFtp::Get || ftp->currentCommand() == QFtp::Put )
