In an effort to ensure that all the media files on your Android device are available in the Gallery app for you to watch or see them, the system performs a check to see if a new media file has been added each time you reboot your device. While that is totally fine for most of us, some of us have files that we do not want to be included in the Gallery app to be viewed by others.

There is a way for you to prevent the Gallery app from scanning specific folders on your device. It does not require you to use a third-party app to get the job done.
