This is a very handy add-on just to have easy access to. If you ever have to make multiple copies of files then this add-on allows you to select the file, how many copies required and then just sit back and watch the magic happen! This app has now been developed to allow you to make copies of Google Drive folders as well! This app works from within Google Sheets as an add-on.
