My photos were in the thousand already and I have saved all files to my laptop harddrive. Here are the steps:
- Open all apps menu and touch-press "File browser" icon.You will be presented with several directories.
- Select /mnt/sdcar/DCIM
- Select Camera under DCIM. thus the full directory path is /mnet/sdcard/DCIM/Camera
- Touch-press the Menu button and select "Delete all". This will delete all files in the desired directory.
