Link to files stored in drive

In a content type I have a links fields using Link Module which has Title and URL set. This is useful to link the external files but I have a requirement to link the files stored in Networked hard disk.

In an intranet system there is a drive eg: Z drive, which is same for all the systems in Intranet. The drive is actually an intranet server which stores all the doc files for everyone's use. When System Admins set-up new computers they set-up in such way that server drive is always Z drive in any computer (company preference).

I have a task to link to the file from Drupal site, lets say the file path is:
z:\popular-documents\how-to-use-pc.docx

When I give the file path to link module, it stores differently like:
http://localhost/Z%3A%5Cpopular-documents%5Chow-to-use-pc.docx

Is there a way to achieve this in Drupal, so, the file link would be displayed as it is and if possible when clicked would open the file (I guess this is not possible from web interface).
