I have a dual monitor , and I dragged one of my folders to my other monitor , very fast , and now I can't see it , The folder is called WWE Themes, I don't know if it's just me or its actually gone
Check inside the folders on your right desktop (including the recycle bin). If your pointer happened to be over one of the folders when you released the mouse button, it could have placed it inside one of them.
If it's not there, right-click on the Windows Logo in the Taskbar > goto File Explorer > Then type WWE Themes in the search box in the top right corner and wait for it to 'search This PC'.
