When you store your documents in a document libary but want to link to a file-share, you might run into a problem.
You can add the “Link to document” content type. But this is restricted to http:// or https:// links only. A file-share can be accessed using the UNC, but this requires the file:// prefix. How to overcome this?
Well, this is what I did. Allow the file type “.lnk”. Create a link to the file-share using Windows Exporer. This will create the .lnk file for you. Add this .lnk file to your document libary and voilá: there’s your UNC link in the document libary!
And, yes, I do know that this issue can also be solved using the out of the box Links app, but in this scenario the requirement was to store these links in the document libary.
