In your Gelato account Library, hover the mouse over a file and you will see options including 'Copy' and 'Move'
Also when you select the checkbox on a file, similar options will appear in the format of buttons at the top of the window. Select 'Copy' or 'Move' and you will see the next screen where the destination Folder is required to be selected for Copying or Moving the selected file to.
If you want to move/remove/share several files at once you can simply do it by clicking on 'select all' option.
