Random Untitled Folders Appearing

Ok so I finally figured out the issue (at least for me). It turns out that some games when you have multiple monitors do not use true full screen and so right clicking can create accidental new folders to appear on the desktop.

In particular the game League of Legends was culprit in this. I found out after doing some more research and noticing this only seemed to occur after the game. There does not appear to be a remedy for this yet.

The desktop preferences you wanted to delete at: ~/Library/Preferences/com.apple.desktop.plist are not located in the root Library folder of your hard drive. Instead you need to navigate within your user home folder at Home/Library/Preferences/com.apple.desktop.plist

If you don't know how to see the Library folder, within the Finder hold down the Option key and click on the Go menu and then select Library from the menu. This will open up the Library folder for you and then you can just navigate to Preferences/com.apple.desktop.plist

Let us know if this works for you.
