Links to files do not work but if links to URLs

[#1]

Hello:

When I create a link from Qlik, I get it to open the Intenet addresses without problem, but I am not able to open files or folders inside the company or local network.

For example, I write in the expression editor:

'File: //192.168.1.220/alfa/'

And the table appears to me:

So far so good, but when I peak the link opens a blank tab of the browser with the address about: blank

Can someone tell me if I'm leaving something?

Best regards

We have already solved it.

We have had to create an FTP server and that the route is by FTP, because Qlik does not allow to open local files or in an internal network. Only can acces by internet: http, https or ftp
