To rename a file or folder right click on the file/folder and and scroll down to “Rename” click on it and change the file name or folder name and press “Enter” when finished.
Another way to change the names of files and folder is to click on it once to select and click it once again to highlight the name in blue and start typing and hit “Enter” when done.
If you cannot change a file name or can not rename a folder check to make sure you do not have it open in a program or a window. Sometimes a computer restart is necessary.
