Duplicating a document enables the users to create a copy for any document. You can modify the content and layout of the duplicate document without affecting the original one.
In the Document portal, select the document for which you want to create a copy.
Click the More button next to the selected document and choose Duplicate from the options.
Click the Duplicate button on the top-right corner of the Document portal.
Note that the duplicate document is saved with the following name, that is, 'Name of the Original Document' + '-Copy'.
For information on renaming a document, see Rename a Document page.
