The file class has two seemingly similar methods Touri () and Tourl (), both of which convert files to a link that can be accessed by the network. URIs and URLs have a wider range of applications than URIs.So why use Touri () instead of Tourl ()? This is easier if you want to convert the file to a URL. Because there is a bug in Tourl ().When file is converted to a URI, the special words in the link will be such as # or! Encoding, and Tourl () does not.If you convert "c:documents and settingstest
