you can use internet explorer perform this task.the steps below:

gsx is my username, gsx.crcoo.com is my website.
2.then , you can press enter key. internet explorer will popup a dialog prompt you input your password to login .
3.when you complete, internet explorer window will become a remote document of your ftp website. you can upload , download ,delete the files or folders of website like your local folder.
4.I tried , use internet explorer can ftp through several sites at once . but it is a simple but not best way to finish ftp work. I suggest you use the ftp software , like leapftp(I used) or cuteftp perform the ftp task.
