I want to add a file on my local drive (C:\something.html) to the Trusted Zone in IE8 (my OS is Windows Server 2003). The Add Sites Dialog box, does not seem to take entries for files on the local drive.

I have tried:


I have seen other solutions (on superuser and elsewhere) such Mark of Web, that allow your local file to be treated as if it were part of the internet zone, but I want to add my file to the Trusted Zone.

How can I do this? Thanks.

I haven’t used IE for a while now, so I don’t know if they changed it, but aren’t all local files (ie My Computer) in the Trusted Zone already? – Synetech Feb 6 '12 at 4:14
In IE9 and IE11, I can see that a local file is considered to be in the Internet security zone. In IE8, it is in Local Computer zone (it's hidden from the security settings dialog). – ivan_pozdeev Jul 5 '14 at 16:34

In Internet Explorer, go to

Tools → Internet Options → Advanced

Scroll down to the Security section and check the box for

Allow active content to run in files on My Computer

Dangerous suggestion :
Install IIS, add C: as a virtual directory, and add localhost to the Trusted Zone.

You can set the permissions to allow IIS access only to some of the directories on C:.

The only other solution I know is Mark of the Web.
