Office2 lets you copy documents from one folder to another or to another name within the same folder. To copy a document, start by tapping on the Organize button in the toolbar at the bottom of the screen.
The toolbar will change to show a Move button, a Copy button and a Cancel button. Select the document (or documents) that you wish to copy, by tapping on each document in turn.
A tick will be shown against each selected document. Then press the Copy button. You will be asked to choose a destination folder.
The top-most level folder is shown initially, giving you the opportunity to choose either a local folder, or a remote folder, such as a folder located in Google Docs or on your MobileMe iDisk. To copy the document locally, tap on Local Files and tap on the relevant sub folders until you have located the desired destination folder.
To copy the document to the chosen folder, press the Choose "folder" button in the toolbar. To cancel the operation at any time, press the Cancel button in the top right of the screen. If you selected a destination folder, which is the same as the source folder, the document name will be changed to original document name_Copy.
