Enable or Disable Passive FTP Mode In Internet Explorer

PASV is less secure than Active FTP

Internet Explorer
 Microsoft

Internet Explorer 6 and 7 are set to use Passive FTP by default. Passive FTP mode is used by some FTP servers on the internet to better work with firewalls. It is a less secure method of connecting than Active FTP. Internet Explorer includes a way to deactivate and activate Passive FTP (PASV) mode. You may need to either enable or disable this setting to allow Internet Explorer to work as an FTP client with a given FTP server. Follow these instructions to make it happen.

Activating and Deactivating Passive FTP Mode

  1. Open Internet Explorer 6 or 7 from the Start Menu or command line.

  2. On the Internet Explorer menu, click Tools to open the Tools menu.

  3. Click Internet Options to open a new Internet Options window.

  4. Click the Advanced tab.

  5. Find the setting called Enable folder view for FTP sites, which is located near the top of the list of settings. Ensure this feature is disabled. It should be unchecked. Passive FTP mode in Internet Explorer does not work unless this feature is disabled.

  6. Locate the setting called Use Passive FTP approximately halfway down the list of settings.

  7. To enable the Passive FTP feature, check the box next to the Use Passive FTP setting. To disable the feature, clear the check mark. 

  8. Click OK or Apply to save the Passive FTP setting.

In later versions of Internet Explorer, enable and disable PASV using Control Panel > Internet Options > Advanced > Use Passive FTP (for firewall and DSL modem compatibility).

It is not necessary to reboot your computer when you enable or disable Passive FTP.
