Disable or Mute Trash Sound How can I disable the sound when deleting a file from Finder in OS X Mountain Lion?

I do not see any specific mention of it under System Preferences or Finder Preferences. I don't want to disable other sounds; just that one.
The sound file for moving an item to the trash is located here:

Go to your HD > System > Library > Components > CoreAudio.component (right click and choose "Show Package Contents") > Contents > SharedSupport > SystemSounds > dock > "drag to trash.aif"

This "drag to trash.aif" is the sound file responsible for the audio effect.

Back up the current file just incase and replace it with a silent one (a quick google search will do - you might need to get the silent file as mp3 and then convert it to aif).

You may need to restart for it to take effect.
