Multipart Posts in Newsgroups

Posts on Usenet newsgroups that are so large they must be split into multiple smaller messages. All parts of the message must be downloaded and reconstructed into one complete message in order to be read. A multipart post is extremely common with most Usenet newsgroups, requiring the need to download multiple headers (see headers) in order to have the complete file that the original sender intended. Many forms of a multipart post exist. Most common extensions range from RAR to ZIP. These packages often times are packed with a utility software to reduce the size of the newsgroup message. External programs are often needed, separate from the newsreader itself, to successfully unpack these Usenet newsgroup messages to reveal the complete file the original sender had intended.
