“Konqueror” is the file manager for the KDE desktop environment for Unix,and only makes sense to use if KDE is running. Some way of reliably detecting KDE would be nice; the KDEDIR variable is not sufficIEnt. Note also that the name “kfm” is used even when using the konqueror command with KDE 2 — the implementation selects the best strategy for running Konqueror. Only on windows platforms. Only on Mac OS X platform.<span >'''
