The following questions are related to handling data and files on the TV.

You can use the FileSystem API to access external USB storage. For more information, see Handling USB Storages and Managing File Operations.

Application data is retained when the TV is switched off or the application is updated. All application data is deleted when the application is uninstalled.

   #application data    #update    #uninstall

When an installed application is updated, the local Web storage on the device is unaffected. The local Web storage data is only deleted when the application is uninstalled.

Note When updating an application test build through the Tizen Studio, the previous build is uninstalled before installing the new build. Consequently, the local Web storage data is deleted.

No. For security reasons, this behavior cannot be modified. If you want to implement additional behavior when a USB storage is connected, use the Filesystem API. For more information, see Handling USB Storages.

Make sure you have declared the "filesystem.write" privilege in your "config.xml" file. It is required for writing data to storage.
