Step by step: Anarchie (Mac)

Open Anarchie. In the "File" menu select "Get via FTP".

In the "Server" field enter your domain name or IP address. In the "Path" field enter "/web". In the "Username" and "Password" fields enter your username and password. Make sure that the "Get Listing" radio button is checked and click "List".

You can now drag and drop files to and from the Anarchie window, just as you would with any window in the finder.
