I've noticed recently that iTunes and QuickTime X seem to be generating an ever-lengthening list of crazy zero byte plist files in ~/Library/Preferences. They have names like com.apple.QuickTimePlayerX.plist.SXyRKFY and com.apple.iTunes.plist.1CcfrdJ. This is in addition to the normal files without the extension. They have a size of zero bytes and are empty when I open them in TextEdit. I deleted all of them a little while ago, with no apparent effect. I just checked and more have started taking their place. I guess its too bad I didnt keep the original ones around, I could have checked to see if the oldest ones creation dates lined up with the release of iTunes 10 or anything. Does anybody else have these files?
