Question

How can I open a local folder view by clicking on any link?

I tried many options like

<a href="file:///D:/Tools/">Open folder</a> or

<a onclick="file:///D:/Tools/">Open folder</a> or

<a onclick="window.open(file:///D:/Tools/)">Open folder</a>

Linking to local resources is disabled in all modern browsers due to security restrictions.

For Firefox:

For security purposes, Mozilla applications block links to local files (and directories) from remote files. This includes linking to files on your hard drive, on mapped network drives, and accessible via Uniform Naming Convention (UNC) paths. This prevents a number of unpleasant possibilities, including:

• Allowing sites to detect your operating system by checking default installation paths
• Allowing sites to exploit system vulnerabilities (e.g., C:\con\con in Windows 95/98)
• Allowing sites to detect browser preferences or read sensitive data

for IE:

Internet Explorer 6 Service Pack 1 (SP1) no longer allows browsing a local machine from the Internet zone. For instance, if an Internet site contains a link to a local file, Internet Explorer 6 SP1 displays a blank page when a user clicks on the link. Previous versions of Windows Internet Explorer followed the link to the local file.

for Opera (in the context of a security advisory, I’m sure there is a more canonical link for this):

As a security precaution, Opera does not allow Web pages to link to files on the user’s local disk
