Deleting a Folder

[JimDaniel]

I don't have time right now to go through your code, but in a past project, I wrote a recursive function to do just what you're wanting to do, you pass it the parent directory path as a string, and it does the rest for you...

void VideoManagerPage::deleteVideoDirectory(QString video_dir)
{
	QDir dvd_dir(video_dir);
 
	//First delete any files in the current directory
	QFileInfoList files = dvd_dir.entryInfoList(QDir::NoDotAndDotDot | QDir::Files);
	for(int file = 0; file < files.count(); file++)
	{
		dvd_dir.remove(files.at(file).fileName());
	}
 
	//Now recursively delete any child directories
	QFileInfoList dirs = dvd_dir.entryInfoList(QDir::NoDotAndDotDot | QDir::Dirs);
	for(int dir = 0; dir < dirs.count(); dir++)
	{
		this->deleteVideoDirectory(dirs.at(dir).absoluteFilePath());
	}
 
	//Finally, remove empty parent directory
	dvd_dir.rmdir(dvd_dir.path());
}

void VideoManagerPage::deleteVideoDirectory(QString video_dir)
{
	QDir dvd_dir(video_dir);

	//First delete any files in the current directory
	QFileInfoList files = dvd_dir.entryInfoList(QDir::NoDotAndDotDot | QDir::Files);
	for(int file = 0; file < files.count(); file++)
	{
		dvd_dir.remove(files.at(file).fileName());
	}

	//Now recursively delete any child directories
	QFileInfoList dirs = dvd_dir.entryInfoList(QDir::NoDotAndDotDot | QDir::Dirs);
	for(int dir = 0; dir < dirs.count(); dir++)
	{
		this->deleteVideoDirectory(dirs.at(dir).absoluteFilePath());
	}

	//Finally, remove empty parent directory
	dvd_dir.rmdir(dvd_dir.path());
}
