thanks... i tried compression as zipfile.ZIP_DEFLATED and it works fine. Now
i used WinRar software to compress a 1.5GB file, it results into a 42MB file
where as using my script it results into 62 MB file. Is it because of
different format, if so, is there any winrar lib or equivalent lib for
python.
ah
