Hello, I am relatively new to the Mac. I have a Macbook Pro 2.2GHz. Today, a file keeps popping up on my desktop. It is named .DS_Store. The icon looks like a text document. I won't open it cuz I'm afraid of what it is, lol (Windows still clogging my brain). Anyway, I can drag it to the trash and delete the trash, but after a bit, it reappears. Any idea how to get rid of it?
