Your Google Drive is made up of a collection of files and folders. If you need to create a new file from scratch, you can do it from right within Drive. After you’ve added a number of files, you may find you need to create folders to keep your work organized.
There may be times when you want to make changes to a file but also keep a separate, unedited version, or you may have a file that will serve as a starting point for a secondary file. Copying a file creates an exact duplicate.
Select a file you want to copy.
Click the More actions button.
Select Make a copy.
You can also right-click a file and select Make a copy from the menu.
