Retreiving only 2K of a file, how?

[MeZodic]

Ok, another ? from me:

How can I retrieve only 2K of a file using either LWP or Parallel ? This 
would speed me up considerably if I could figure out how to save only 2K of a 
file instead of having to save the entire document!! Pretty please someone 
show me how.......thank you....
