How the Finder misbehaves on USB sticks…
As a new Mac user I find it very annoying that the Finder leaves its traces everywhere you go — even on USB sticks. 
The finder will create hidden .DS_Store and .Trashes folders (used by SpotLight and the Trashcan) all over the place.
I’ve not yet found a way of disabling this unwanted behavior.
If you know of a way to do so, I definitely want to hear from you. So, please step ahead and leave a comment!
