    I have some useful manuals etc that might be of interest but they are
    too large to post singly (my news provider rejects them). Around 1 MB or
    so.

    I'm only using Netscape 4.8 (because I like it before anyone makes sarcy
    comments).

  2. Have you looked at putting them on BAMA?

    I haven't come across BAMA. Could be useful but I had design manuals rather
    than operator /service manuals in mind.

    Interesting site though.

    WinZip and WinRAR each have the ability to split compressed files. IIRC,
    in WinZip one creats a .zip file and then asks for it to be split; in
    WinRAR the splits are created on the fly.

    There are various other utilities out there to create splits from
    original files; not that hard to write. The advantages to using WinZip
    or WinRAR are having a standard format, an easy way to recombine the
    files, and built-in error checking.

    If it's a LOT of files in one split, consider also passing the lot
    through QuickPar, which enables the recovery of missing pieces if enough
    of the base material made it though.
     
  6. Hard to believe that you have been in Usenet for this long and do not
    know how to post a binary.

    Hint: It is not a Nutscrape process.

    Sections must be kept below 10k lines each.

    The binary must be converted to ascii only. UUencode is the norm.
     
  7. When the only **** you have is ****, everything looks like *****.

    Try unix "dd if=bigfile.ext of=part00 bs=1048576 count=1 skip=0"
    "dd if=bigfile.ext of=part01 bs=1048576 count=1 skip=1"
    "dd if=bigfile.ext of=part02 bs=1048576 count=1 skip=2"
    "dd if=bigfile.ext of=part03 bs=1048576 count=1 skip=3"
    ..

    Silly donkey...

    Open up Outlook Express, check the news settings that it will split up posts
    over, say, 500kB, then go ahead and attach and send. The (1/3), (2/3), etc.
    bullshit is added automatically. And multipart assembly is a menu item
    away.

    Once again, OE wins. ;-)

    the one time I posted a large binary I used newspost (it's a command-line thing)

    splitting large uuencoded binaries by hand is while a "trivial" task, easy to
    foul up.
    the only important header is the subject line, MIME does not support
    file-splitting and so cannot be used to transmit large files.

    (you could split the file first (eg: using rar) and then require the
    recipient to reassemble them

    10000 lines uuencoded (standard 62 char line length) is 450000 bytes (of
    original data) but theres atleast three wrapper lines added, so if
    pre-splitting do it to 449865 bytes or smaller

    Some medications can do that too. Fortunately there's a blue pill to counteract
    them !

    True of my father too (he had a devastatingly stupid and ignorant blonde bint 22
    years younger than him) but he only made it 48.

    Doesn't your ISP provide a "personal web page"? Every ISP I've ever had
    has.

    Thanks,

    N+1 steps
    fragment the file, create N posts, (or is there one-step way to select a bunch
    of files an create a message for each?)
    most news client software handles uuencoded files just fine.

    Winrar. As a plus, it also compresses them. Often, smaller than zip.
     
  18. How about IZArc.org It's free. "Create Multi-Volume Set". Plus it
    pretty much replaces all the other programs.

    I was about to say 'stange behaviour' but maybe he simply missed someone he could
    talk to about intimate matters ?

    I should point out above the the stupid blonde bint only came on the scene after my
    mother died when I was 14 but he was also apparently shagging the private nurse he'd
    employed to care for her on the side. In view of her looks I can't blame him ! She
    was a stunning Chinese - unusually tall for them. Ms Wong IIRC. At least she was a
    generally nice person rather than the blonde who went on to do all manner of horrible
    things include introduce my sister to orgies. And much much more !
