Hi, I am a novice Mac user. I own a 2010 Mac Mini OS X 10.6.8 and I have a question. I was dumb enough to delete everything in the username/library/preference folder. I accidentally deleted everything in the folder after reading this: http://www.rahulnair.net/blog/2008/03/17/fixing-vlc-player-crashes-on-mac-os-x/ Basically, my VLC Player had some issues and kept on crashing. I updated the software and the VLC Player is working just fine now. The only concerns that I have is... should I be worried about deleting these files in the preference folder? Other than the fact that I lost my previous preference settings, I have no problems. *edit* I guess I wasn't clear about the question I was asking... Do I damage the hard drive by deleting these files? Or deleting these files won't have any affect on my computer?
