Can you delete pictures on a Sony G camera all at once?

Hi,
If you want to delete selected pictures, follow below procedure:
Press Play button that is located under navigation buttons, see the picture in lcd that need to be deleted, press Delete button located it lower right corner, camera will ask confirmation, press OK by center button in navigation buttons to delete selected picture.
If you want to delete all pictures at once, go to Menu and select Format option to delete all pictures/ video clips etc in memory card.
Click Sony Support to download DSC-S730 camera user manual and check page-15 for details.
Thanks.

Easiest way...go into the menu and find "format"...follow the on-screen instructions.

re format you memory card in camera it should be in menu then settings then memory try it

After you download all the pictures, format the memory card will delete all the pictures on the card.
Here is a link for the user's guide Sony Cyber-Shot DSCW30/W40/W50/W70 Uesr’s Guide

Power up camera, press Home, Memory management, format, OK
That will delete all pictures on memory stick at once.

it could be that it is still saved in the cam memory or memory card, erase both.

Hi,

Unfortunately, there is no option to do this on the camera. I would recommend connecting the camera to the computer and then delete from there. It will be way faster and easier.

Turn on your camera and go to menu select set up. Then select memory stick it is under the highlighted camera, Then click on format. Go to ok then click ok. Then your camera will read all data in memory will be erased. Then click OK. Now your on your way to a clean memory stick.

you can just use the format menu on the setup menu
