how can 1 obtain changed file names qfilesystemwatcher directorychanged event? you need connect slot filechanged() signal instead of directorychanged() if more interested in file names. connect(&myfilesystemwatcher, signal(filechanged(const qstring&)), slot(handlefilechanged(const qstring&))); then, can use slot argument desired. here, printing out stdout: void handlefilechanged(const qstring &path) { qdebug() << path; } please see documentation further details: void qfilesystemwatcher::filechanged(const qstring & path) [signal] this signal emitted when file @ specified path modified, renamed or removed disk. not sure how familiar qt signal/slot system, if not enough, please go through this, too: qt signals & slots
