How to convert a Tableau Packaged Workbook (twbx) to Tableau Workbook (twb)? -

i working tableau packaged workbook , looking convert tableau workbook, i.e. pure file without data extract in file. i've tried open file in tableau, go data source , select "live" connection instead of "extract". file size did decrease dramatically, file name extension didn't change, instead stayed ".twbx" instead of ".twb". can change manually, mess file? thanks!

btw, using tableau 9.0 desktop.

just found answer. actually, need open twb file in tableau desktop , go file - save - save type - tableau workbook.
