reply to Rojo Are you running any of those system optimizer or cleaner tools? All of those files look like cache files, which those tools love to remove. -- -Ryan I use Linux, OS X, iOS and Windows. Let the OS wars die.
I often see a Removed Files.bundle folder in my trash after an app gets updated. I have assumed it's the bundle of old files replaced by the new version of the app. I never looked in the folder like you did though, next time I will.
