Alternate method in Windows 7
If you want to upload files, delete files, or rearrange the folder structure on an FTP site, you need to open the site in Windows Explorer. If you just want to open FTP sites and download files from them, you can use Internet Explorer. Here's how to create a shortcut to an FTP site so that the site will automatically open in Windows Explorer:
To create a shortcut to open an FTP site in Windows Explorer
Click to open Computer.
Right-click anywhere in the folder, and then click Add a Network Location.
This displays the Add Network Connection wizard. Click Next.
In the wizard, select Choose a custom network location, and then click Next.
Enter the name of the FTP site, with the full FTP:// in front of it, and then click Next.
To use a name and password, clear the Log on anonymously check box. Type a user name, and then click Next.
By default, the name of the shortcut is the same as the FTP address. If you want to give the shortcut a different name, type it in the Type a name for this network location box. Click Next.
If you do not want the FTP site to open after you're done setting up the shortcut, clear the Open this network location when I click Finish check box. Click Finish. A shortcut to the FTP site appears in the Computer folder. You can drag that shortcut to your desktop so that it's easy to find later.
When you first connect to the FTP site, you’ll be prompted for a password. Select the Save password check box if you want Windows to remember that password and connect you directly to the site in the future.
