Assign the file url to the file path

Assign the file url to the file path

[Issue] Internal bug in RSA binary

[Problem] The file sending is fail in the file viewer

[Cause] In file view, store the file path without URL info. (file://)
        So we get the file path to NULL using g_filename_from_uri

[Solution] 1. Request to add URL info (To the viewer part)
           2. Add the protect codes in our code
