Get directory of QString

[Astrologer]

Hi there. I have a QString which contains a full path to a file. I need extract the directory out of it. And then I need create the directory with certain name specified by the second QString.

QString full_path_name("c:\\folder1\\mynewJPG.jpg");

QString full_path_name("c:\\folder1\\mynewJPG.jpg");

To copy to clipboard, switch view to plain text mode 

I want the final QString to be like this - "c:\\folder1\\myNewJPG.files\\". Thank you so much in advance.

Solved.

QString current_jpg_name("c:\\myFolder\\jpg.jpg");
QFileInfo fi(current_jpg_name);
    QString folder_name = fi.baseName();
    folder_name.append(".files");  // "jpg.files"
 
    QDir tmp_dir(fi.dir());// "c:\\myFolder\\"
    tmp_dir.mkdir(folder_name); // "c:\\myFolder\\jpg.files\\"

QString current_jpg_name("c:\\myFolder\\jpg.jpg");
QFileInfo fi(current_jpg_name);
    QString folder_name = fi.baseName();
    folder_name.append(".files");  // "jpg.files"

    QDir tmp_dir(fi.dir());// "c:\\myFolder\\"
    tmp_dir.mkdir(folder_name); // "c:\\myFolder\\jpg.files\\"
