A little “fun” Qt5 console application to create a directory (a.k.a. folder) ending with a space character (” “). This directory can not be removed with standard Windows tools, including most console applications.
#include <QCoreApplication> #include <QDir> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); QString evil_dir_name("Remko is a little Evil !!! "); for(int i=1; i<a.arguments().count(); i++) { if(a.arguments().at(i).compare("-d", Qt::CaseInsensitive) != 0) { evil_dir_name = a.arguments().at(i); evil_dir_name.append(" "); break; } } if(a.arguments().contains("-d")) { if(QDir(evil_dir_name).exists()) { QDir().rmdir(evil_dir_name); } } else { QDir().mkdir(evil_dir_name); } return 0; }
