I am new to this, so please excuse my ignorace if I've overlooked something simple. I've been ripping DVDs for years, but just getting started on Bluray. I have ripped a couple discs using MakeMKV and Handbrake following this guide: lifehacker.com/5559007/the-hassle+free-guide-to-ripping-your-blu+ray-collection When it's done and I go to the source folder to delete the files I no longer need, everything freezes up and I get a "Windows Explorer has stopped working and needs to close" window. I'm not able to access those files at all. I've tried to drag them to the desktop real quick, before the error window opens, but I can't get it done. My computer is less than a month old, I'm running Windows 7 HP, and have an Intel core i7 processor. Any ideas?
