Tally 9 A/c Year Extraction

 How do I extract a particular year from a tally data file.

For example if my tally data file is from 1-4-2002 to 31-3-2009.

And my auditor asks for my AY 2006-07 tally details. Since the file is too big I would like to send only the 2005-06 FY data...for this how do I extract only the year 2005-06 from my main tally data file to a separate data file which wud only contain the 2005-06 data and nothing else.
