Copy a File
Open the file you would like to copy by clicking on that file in the left hand file tree. Click Copy.
Because you cannot have two files by the same name in one folder, you must either select a different destination for the file you are copying or change the name of the file. To change the name, double click the file name in the red box and the window will turn white. Edit the name by typing the new name in place of the existing name, making sure to keep the original extension (.html, .tpl, etc.). After editing the name, click Save button next to the filename.
If you want to keep the file in the same folder, you can finish the copy process by clicking the Submit button in the bottom right of the page.
If you plan to move the file you are copying, select a new parent folder to which you want to move the file by clicking on that folder in the file tree on the right side of the page before clicking the Submit button.
Note - Not specifying a new folder will place the copied file in the same directory from which it was copied.
