Preference files stored in that location can affect all users of your machine, so the implications are a bit far-reaching. Another important thing to know is that some preference files live within the /Library/Preferences folder at the top level of your hard drive, but you’ll need to be a bit more cautious mucking around in there (and you’ll have to authenticate as an administrator to make any changes if you’re not already logged in as one). If the problem isn’t resolved by that, you can always put the old preference file back where you got it (with the application in question not running), and all of the customization options you chose for that program will return. Or tell other people what you’ve done so they can pat you instead, which may be more satisfying.

One of the more common causes for unusual behavior on the Mac is a corrupt preference file, especially if the symptom is a program that won’t open or one that crashes frequently.
