Try this:

$file_data = file_get_contents('filename', false, null, 230);
file_put_contents('filename', $file_data);

I don't suggest this route with files that are in the hundreds of
megs :) But admittedly, it's the simplest solution for small files.
Also, can't use it if you're stuck with PHP 4 since it doesn't support
file_put_contents(). PHP4 is dead now anyways, supposedly, so I read
someplace ;)

Cheers,
Rob.

30 seconds alternative:
<?php
$fh = fopen($file, 'rb');
$f2 = fopen('temp', 'wb');
fseek($fh, 230);
do {
fwrite($f2, fread($fh, 4069));
} while (!feof($fh);
fclose($fh);
fclose($f2);
rename('temp', $file);
?>
