Yes, by (IIRC) asking the filesystem to do this in a simple operation. Most (all?) filesystems support this operation either directly or with little effort. > Is there a way to throw away, say, the first X bytes of the file, > and leave the rest?

The built-in 'file' type doesn't support it. -- \ "It's easy to play any musical instrument: all you have to do | `\ is touch the right key at the right time and the instrument | _o__) will play itself." -- Johann Sebastian Bach | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
