That's unfortunate.  The internet is in general specified to use
big-endian.  For files you'd be well advised to apply the same rule.

Always use htonl to write to files/network and ntohl to read from
files/network.

Granted, but then bits are usually gathered into bytes by the hardware,
so the issue doesn't concerns us programmers, in general.  That said,
some hardware protocols transmit bytes in little endian bit order, while
others transmit them in big endian bit order too :-)

Or if the debate is worthwhile :-)
