Removing a non empty folder in Qt

Question

How to remove a non-empty folder in Qt.

Answer 1

If you're using Qt 5, there is QDir::removeRecursively().

Answer 2

Recursively delete the contents of the directory first. Here is a blog post with sample code for doing just that. I've included the relevant code snippet.

bool removeDir(const QString & dirName) {     bool result = true;     QDir dir(dirName);      if (dir.exists()) {         Q_FOREACH(QFileInfo info, dir.entryInfoList(QDir::NoDotAndDotDot | QDir::System | QDir::Hidden  | QDir::AllDirs | QDir::Files, QDir::DirsFirst)) {             if (info.isDir()) {                 result = removeDir(info.absoluteFilePath());             }             else {                 result = QFile::remove(info.absoluteFilePath());             }              if (!result) {                 return result;             }         }         result = QDir().rmdir(dirName);     }     return result; } 

Edit: The above answer was for Qt 4. If you are using Qt 5, then this functionality is built into QDir with the QDir::removeRecursively() method .
