 <a class="link" href="GAppInfo.html" title="GAppInfo"><span class="type">GAppInfo</span></a> and <a class="link" href="GAppInfo.html#GAppLaunchContext"><span class="type">GAppLaunchContext</span></a> are used for describing and launching
 applications installed on the system.
 </p>
 <p>
 As of GLib 2.20, URIs will always be converted to POSIX paths
 (using <a class="link" href="GFile.html#g-file-get-path" title="g_file_get_path ()"><code class="function">g_file_get_path()</code></a>) when using <a class="link" href="GAppInfo.html#g-app-info-launch" title="g_app_info_launch ()"><code class="function">g_app_info_launch()</code></a> even if
 the application requested an URI and not a POSIX path. For example
 for an desktop-file based application with Exec key <code class="literal">totem
 %<code class="literal">U</code></code> and a single URI,
 <code class="literal">sftp://foo/file.avi</code>, then
 <code class="literal">/home/user/.gvfs/sftp on foo/file.avi</code> will be
 passed. This will only work if a set of suitable GIO extensions
 (such as gvfs 2.26 compiled with FUSE support), is available and
 operational; if this is not the case, the URI will be passed
 unmodified to the application. Some URIs, such as
 <code class="literal">mailto:</code>, of course cannot be mapped to a POSIX
 path (in gvfs there's no FUSE mount for it); such URIs will be
 passed unmodified to the application.
 </p>
 <p>
 Specifically for gvfs 2.26 and later, the POSIX URI will be mapped
 back to the GIO URI in the <a class="link" href="GFile.html" title="GFile"><span class="type">GFile</span></a> constructors (since gvfs
 implements the <a class="link" href="GVfs.html" title="GVfs"><span class="type">GVfs</span></a> extension point). As such, if the application
 needs to examine the URI, it needs to use <a class="link" href="GFile.html#g-file-get-uri" title="g_file_get_uri ()"><code class="function">g_file_get_uri()</code></a> or
 similar on <a class="link" href="GFile.html" title="GFile"><span class="type">GFile</span></a>. In other words, an application cannot assume
 that the URI passed to e.g. <a class="link" href="GFile.html#g-file-new-for-commandline-arg" title="g_file_new_for_commandline_arg ()"><code class="function">g_file_new_for_commandline_arg()</code></a> is
 equal to the result of <a class="link" href="GFile.html#g-file-get-uri" title="g_file_get_uri ()"><code class="function">g_file_get_uri()</code></a>. The following snippet
 illustrates this:
 </p>
 <p>
 </p>
 <pre class="programlisting">
 GFile *f;
 char *uri;

 file = g_file_new_for_commandline_arg (uri_from_commandline);

 uri = g_file_get_uri (file);
 strcmp (uri, uri_from_commandline) == 0; // FALSE
 g_free (uri);

 if (g_file_has_uri_scheme (file, "cdda"))
   {
     // do something special with uri
   }
 g_object_unref (file);
 </pre>
 <p>
 </p>
 <p>
 This code will work when both <code class="literal">cdda://sr0/Track
 1.wav</code> and <code class="literal">/home/user/.gvfs/cdda on sr0/Track
 1.wav</code> is passed to the application. It should be noted
 that it's generally not safe for applications to rely on the format
 of a particular URIs. Different launcher applications (e.g. file
 managers) may have different ideas of what a given URI means.
