It used to be but these days not so much, real-time defrag is nothing but a pain in the arse and for a full defrag solution nothing is quite as fast and simple as defraggler.
Try it and see...it won't cost you anything... Defraggler is not everybody's cut of tea... EDIT: O&O Defrag 11 Pro will install on Win 7 64bit if 2000 compatability is installed first... ________ Vapor info
