Hi, Iffath,
Thank you for considering Sony Community!
Performing a full format recovery will erase all your personal files and third-party software. It will also reset all the settings. The unit will go back to factory default settings.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
VIncent
