[JAVA] Since the image of the lock screen of Windows 10 is beautiful, I wanted to make it a slide show of wallpaper

Isn't the image of the lock screen of Windows 10 beautiful?

The image of the lock screen of Windows 10 is beautiful and it changes regularly, so it's good. Wouldn't it be great if you could stock this up and slideshow it with wallpaper? I'm happy.

Try to find out where it is stored

When I asked Mr. Google, it seems that it is on the following pass. C: \ Users \ (user name) \ AppData \ Local \ Packages \ Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy \ LocalState \ Assets

By the way, it seems that you can also go by typing the following with Run (Win + R) by specifying the file name. %LOCALAPPDATA%\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets

Actually look inside the folder

It doesn't have an extension, it looks like the size of the file, it's probably not the size that makes it a wallpaper, or maybe it's an image that seems to be used as an icon.

For the time being, if you add .jpg to the file, it will be recognized as an image.

Copy to My Picture by separating only those that can be used as jpg

For the time being, the path of My Pictures is "C: \ Users \ (user name) \ Pictures ".

//Path separator
String spa = FileSystems.getDefault().getSeparator();

//Copy source folder
Path fromFolder = Paths.get("C:\\Users\\Kerlon\\AppData\\Local\\Packages\\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\\LocalState\\Assets\\");
//Copy destination folder
Path toFolder = Paths.get("C:\\Users\\Kerlon\\Pictures\\");

//Loop on the file at the copy source
for (String fileName : fromFolder.toFile().list()) {
    //Import the file as an image
    BufferedImage image = ImageIO.read(new File(fromFolder + spa + fileName));

    //For 1920x1080 size
    if (image.getWidth() == 1920) {
        //Copy source file
        Path fromFile = Paths.get(fromFolder.toFile().getAbsolutePath() + spa + fileName);
        //Copy destination file(extension.Add jpg)
        Path toFile = Paths.get(toFolder.toFile().getAbsolutePath() + spa + fileName + ".jpg ");

        //Confirm the existence for the time being
        if (!toFile.toFile().exists()) {
            //Copy execution
            Files.copy(fromFile, toFile);
        }
    }
}

I'm glad that I was able to copy only the 1920x1080 size image to My Picture.

Tweak Windows wallpaper settings

Right-click on an empty area of the desktop and select "Personalize".

Make the following settings

--"Background" to "Slideshow" --"Choose a slideshow album" to "Picture" ――The rest is as you like

Make it run on a regular basis

Insert the executable file into the startup. If you do this, it will be executed automatically at startup. For those who do not turn off the power of the PC, it is recommended to use "windows start menu-> all programs-> accessories-> system tools-> task scheduler".

Congratulations
