I have created URL field in opportunity for showing local/Network files in browser window.

While clicking URL field, URL changed in browser window.
Local File path:
Actual URL :  F:\Salesforce\TargetFolder
Changed URL : http://f/Salesforce/TargetFolder

We cant access file path.

I have used another mothod, its also not working. 
Created fields 
Folder path (Folder_Path__c)            - Text Field 
Folder path view (Folder_Path_view__c) - Formula Field
Formula  - HYPERLINK("file://"&Folder_Path__c,"View File");

While clicking the links, it showing the below errors

Chrome  - "about:black"#blocked
Firefox - "about:black"#blocked

if copy and paste the link in new tab its working fine. (Copy Link Address)  

How to solve the security issue without adding any browser extension.

Does anyone have any new idea to solve this issue.

Thanks,
