    When I usually download binaries of songs, X-News converts them to mp3
    but I downloaded files from a radio talk show today and they were PAR2
    files. How do I convert these to mp3?

    Thanks,
    Warren

    You don't. A PAR file isn't the song file. Allow me to explain.

    Binary postings on Usenet often are uploaded as compressed archives like
    ..Zip or .RAR. When you download all the parts of the multipart binary file,
    your newsreader should automatically reconstitute the file for use. Now, as
    you say, you are used to downloading the posts and getting an MP3 file. What
    has happened is that the person who posted the file, compressed it into an
    archive first. In this case, he/she used ".RAR" archive compression. The
    ".PAR" file you got was merely one of the "repair" files that often
    accompany .RAR posting these days. Someone came up with an ingenious idea on
    how to fix corrupted or incomplete .RAR posts by creating a "Parity" set of
    files that can be used to repair a problem in the main archive .RAR files.
    When you see this, you will see typically several parts that comprise the
    ..RAR archive file or files (RAR, R01, R02, etc) and then a short series of
    "PAR" files (PAR, P01, P02, etc). When a person downloads the .RAR posts and
    saves them to his/her harddrive, they can then be opened with a program such
    as "WinRAR" which will extract the archived files within. But, if the
    archive is corrupt, has parts missing, or otherwise incomplete, that is
    where the parity files come in. Using a program such as "SmartPAR", or
    "QuickPAR", etc. you open the downloaded .PAR file, and then the program
    will examine all the downloaded parts of the .RAR archive and check their
    integrities. If a problem is found with them, and you have downloaded enough
    ..PAR files, and parts of the .RAR archive itself, then the program can
    usually repair the problem, resulting in a complete and corruption-free .RAR
    archive file, which can then be opened by WinRAR or other archiving programs
    that recognize .RAR files. Then you can extract your music file within, if
    that is what it contains. So what you downloaded was only a portion of the
    repair files, and that alone will not get you the music file you wanted to
    download. Look for more posts with parts of that archive. It's also entirely
    possible that the rest of the parts are expired from the server, or didn't
    make it to your news server at all.
