HavenТ‘t you ever met with http:// or ftp:// links with unknown file size. Sometimes, file size is determined incorrectly. But it is a not problem with Internet File Size. Now you can easily determine file size, type and modification date in the internet. Moreover, if your base http or ftp link is "encoded" (such as http://www.server.com/downloadfile?id=34532), Internet File Size shows real file http or ftp path.
