What is a .DDW file?
A .DDW file is a special kind of computer file that is used to change the background picture of your computer screen throughout the day. This file works with a program called WinDynamicDesktop. The idea is that your computer's wallpaper can change to match the time of day where you are, like showing a bright picture during the day and a dark one at night.
The .DDW file is like a box that holds several items inside. It is made using a method called Zip compression, which means everything inside the box is squeezed to take up less space. Inside this box, you will find pictures in .JPG format, which are the different wallpapers that will appear on your desktop. There is also a .JSON file, which is like a list that tells the WinDynamicDesktop program information about the theme, such as the names of the pictures and when they should be shown.
To use a .DDW file, you need to have the WinDynamicDesktop program installed on your computer. Once you have this program, you can open the .DDW file with it, and it will automatically know how to use the pictures inside the file to change your desktop wallpaper at different times, like showing a picture of the sunrise in the morning and a picture of the stars at night.
In summary, a .DDW file is used with the WinDynamicDesktop app to make your computer's background change with the time of day, and it contains pictures and information for the app to use.
