split. I know it exists on cygwin; if you don't have
it the C is extremely short.

If you're not used to the split command, it turns a
large file into many small fixed line/byte/block count
files with names like "aaa", "aab"... Its original use
with with uucp for sending over-large uuencoded files
(anyone else rememer bang paths?).

For your purpose you'd have to double the file size

    cd /tmpdir;
    split -blah /inputfile;

you now have a few zillion, say, 1MB files.

That or grab a dos-ified version of dd to handle the input
and output buffering. You could fix the i/o size into blocks
the O/S can gracefully handle.
