Is FTP deprecated by W3C, and if so, what is the suggested replacement? And why is File Transfer Protocol more dangerous for file transfers than hypertext transfer protocol? Does HTTP provide a method to compare a downloaded file with the original as is possible with FTP? Or is FTP more dangerous than HTTP because the security of an FTP server against unauthorized intrusion modifying its downloadable files is inherently less than that of an HTTP server against an analogous attack?
TC's built-in updater is fine for those who have unmeasured wideband internet connection, and for those who only have a single-copy license, but if you have copies on multiple machies, and a slow or measured internet connection, it requires multiple downloads of the same file, an obvious waste of bandwidth and download volume. Thanks to the update information (.aiu) files, I can minimize the download volume even with HTTP, but I must depend on the hash codes in the .aiu files as the sole means to verify download accuracy, I cannot compare with the originals.
