When you copy and paste a file , you're making a duplicate of the original file that you can then modify independently of the original file. If you copy and paste a file to a different location on your computer, it's a good idea to give it a different name so that you'll remember which file is new and which file is the original.
Open the location that contains the file you want to copy.
Right-click the file, and then click Copy.
Open the location where you want to store the copy.
Right-click an empty space within the location, and then click Paste. The copy of the original file is now stored in the new location.
For information about copying multiple files, see Select multiple files or folders.
Another way to copy and paste files is to use the keyboard shortcuts Ctrl+C (Copy) and Ctrl+V (Paste).
You can also press and hold the right-mouse button and then drag the file to the new location. When you release the mouse button, click Copy here.
You can copy and paste a folder the same way you would a file. When you do this, all the files in the folder are copied as well.
