Your best friend for file transfer.Fetch
The Duplicate command either duplicates files on a server, or duplicates a shortcut in Fetch Shortcuts or another shortcut list window.
This command is available as:
When one or more files are selected in a file list, the Duplicate command lets you duplicate them. It does this by using a server-to-server transfer. Fetch opens a second connection and transfer window to the server, and transfers the file from the server to itself, resulting in a new copy of the file. The name for the new file is chosen by the server, so while it should be a variant of the original filename (such as "myfile.1" for a duplicate of "myfile"), some servers will assign a meaningless name.
When a shortcut is selected in Fetch Shortcuts or another shortcut list window, the Duplicate command makes a copy of that shortcut in the same window. You can then edit the new shortcut to make any changes. This is handy if you want to make a set of very similar shortcuts.
