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 requirements also 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 above file path to link field, it changes the whole Link completely like:
http://localhost/Z%3A%5Cpopular-documents%5Chow-to-use-pc.docx

How can I use Link Module to link to the file and display the file link as it is instead of having http:// which link module adds by default.

The reason I have to use Link Module is I also want to be able to link it to external files too, lets say Google docs.

Not a requirement but good to have, if possible when the link is clicked it would open the file (I guess this is not possible from web interface).
As I also stated in my comment, try to give a real network path. For example if the shared folder Z: is mapped to \\server\folder, the real network path of the file would be:


  file:///\\server\folder\popular-documents\how-to-use-pc.docx


UPDATE:

According to Link module page:


  Filter allowed protocols module This module allows you to change the default protocols that are set by Drupal to include new protocols like skype. The default protocols, for reference, are 'ftp', 'http', 'https', 'irc', 'mailto', 'news', 'nntp', 'rtsp', 'sftp', 'ssh', 'tel', 'telnet', and 'webcal'.


You can try this module to include 'file://' protocol.
