I was trying to delete the hidden files on my USB stick through my Mac when after deleting some of the files there was a file called ".DS_Store" on my desktop. I went and moved it to the trash but once I clicked "Empty Trash" is duplicated itself back to my desktop on its own. I was using a program called Houdini 3 to see and delete my hidden files and now that its on my Mac I was wondering if it shows all the hidden files now and this ".DS_Store" was one of them hidden on my desktop. I have no idea, I just need some help deleting this annoying file.
