Ouch! Sorry for the mistake. You are of course right.

$ file ~/public_html/datafiles.tar.bz2 
/home/ajayshah/public_html/datafiles.tar.bz2: gzip compressed data, from Unix
$ cd public_html/    
$ cp datafiles.tar.bz2 datafiles.tar.gz  
$ update-page

So the old file (datafiles.tar.bz2) is still there as is the correct
file datafiles.tar.gz
