 Like other URI protocols, web browsers can be configured to automatically handle ed2k URIs.After installing an eD2k client, the eD2k protocol is optionally registered so that clicking on it in the browser automatically starts the download or asks whether the user wants to start downloading.File links are preceded with the "file" token, which indicates that this is a file link, as opposed to a codice_1, codice_2, codice_3 or codice_4 link.
