Windows 7 supports multiple desktop background switching functions to make our desktop more beautiful, but for users who like to save images according to folders, if you specify a folder containing subdirectories when setting the desktop background, such as "wallpaper", but there are several sub-directories such as "landscape" and "animal". When displaying the desktop background, only the pictures under the wallpaper folder can be displayed, and the pictures in sub-directories such as "landscape" cannot be displayed.
