Link from Document Library to UNC Path

Question

Can anyone tell me if it is possible to create a link from a document library to a UNC path?
I need to establish links to resources in an existing document repository, but Sharepoint presents the following message when attempting to add the link "Enter a valid document name and URL. Valid URLs must begin with 'http:' or 'https:'"
Thanks in advance.

Following are the steps to achieve this.
1) Create a site content type of type "link to a document" with "Document" as a parent content type.
2) Add the same to the document library.
3) Go in the layouts folder open newlink.aspx in Visual Studio IDE
4) add the following function to the script tag
Code Snippetfunction HasValidUrlPrefix_Override(url)
            var urlLower=url.toLowerCase();
            if (-1==urlLower.search("^http://") &&
            -1==urlLower.search("^https://") && -1==urlLower.search("^file://"))
            return false;
            return true;
 5) Replace "HasValidUrlPrefix" to "HasValidUrlPrefix_Override" in the newlink.aspx
6) IISReset and when adding a link to a file share. It shoudl be done in the following format "file://\\{ComputerName}\\}FileName}" it should work
7) Change the wss resource file present in app_globalresources to show the following message "Enter a valid document name and URL.  Valid URLs must begin with 'http:' or 'https:' or 'file://'"
Hope this should help.
