Some applications may have registration information stored there. Others may have trouble running as things are put there when you install. You’ll lose all your preferences for things like your browser, the Finder, etc. Is there some reason you want to do this? If so, what? Imacer 10 years ago I was just going through my home folder and wanted to clean it up. Get reed of all unnecessary files. No other reason. Gary Rosenzweig 10 years ago In that case I would leave the preferences folder alone. I would only delete a file there (or anywhere) if you knew exactly what it was, why you didn’t need it anymore, and how getting rid of it would affect things. Imacer 10 years ago Thanks, Gary for the tip.
