Options presented in the Updates tab of the Global Preferences window allow you to perform update checks via an HTTP proxy server.
To use an HTTP proxy server when performing update checks, select the "Use HTTP proxy server" check box and provide a proxy port and address (either a host name or an IP address).
If your HTTP proxy server requires authentication, please populate the Login and Password fields appropriately. Otherwise, leave these fields blank.
•Automatically check for updates - When enabled, Duplicate File Detective will check for updates whenever it is started. This will occur in the background, and a small tray notification area window will be shown if a newer version of the application is available.
