Store a shared directory file ib a field and be able to open it

We have a requirement where files are stored on a local server share which the client wants to be able to access from a filed within CRM. 

Would it be possible to have a URL (or any other field for that matter) open a file on a UNC path (\\Server2\Share\Test\Foo.txt) or (file:///Server2\Share\Test\Foo.txt)
