.DS_Store
A document named .DS_Store appeared a few months ago. The name starts with a period. .DS_Store. It shows up as you see in this screenshot at the top of everything I do. You can see it is grayed out. I want to know what it is and how I got it and can I get rid of it. What is it doing? I put it on my desktop to get info.
( for the subject of this post it says ......mac with os windows ntclienttip I did not type that. what is mac with windows ntclienttip?) I ask because I think I remember reading that things that start with a "." are windows files and I dont have a windows system on my mac.
