By default, if nothing exists in the folder, your site should issue a 404. If you explicitly want to hide a folder / file from being accessed (which would throw a 404), you could just configure the directory (or file) in either IIS or your web.config via hiddenSegments:

<system.webServer>
    <security>
        <requestFiltering>
            <hiddenSegments>
                <add segment="yourDirectoryToHide" />
            </hiddenSegments>
        </requestFiltering>
    </security>
</system.webServer>

Thanks for the replay.

But I don't want to hide the folder. Actually, in my folder I have some PDF files for version 1.0 now I am releasing another latest version 1.0.1 so if the users try to access the old files 

i.e., filename.1.0.pdf then a message should come "please login to the site and download the latest version of the file" this message should come instead of 404 message only when user trying to access the files from this folder  any other files  or aspx pages if he is accessing then normal 404 message will come which I redirected to a specific page in web config

as below

<customErrors mode="On" defaultRedirect="pagenotfound.aspx">
<error statusCode="404" redirect="pagenotfound.aspx" /> </customErrors>

My IIS server IIS 7

Please suggest

Hi nagapavanich,

Accroding to your description,I suggest you could insert  url rewrite in web.config and come out error 404.
