Nevermind speed, locking is the problem.
> Windows 8.1 outperforms the latest Ubunto in copying large files if that's what you mean.
I guess I will have to grab some of my BD images and find a Win8 box then.
Although the problem with Windows in this regard really isn't speed. Something like this is really more of a batch job. The problem with Windows is it's stupid locking and how it handles that locking during a large copy operation. What should be a partial fail becomes a total fail.
Then you need obscure and arcane tools to work around what should be a simple single drag and drop operation that your great grandma could handle.
This approach also makes it harder to deal with malware/adware that piggybacks on freeware and shareware packages for Windows. I should be able to toast any DLL if I want to.
