Move window to another screen?

Great Dustin, that works nicely. Thank you so much for your help on this. I'm using similar code to try to manipulate the windows to half screen (and will get to thirds at some point), but I can't get it to work reliably like the quarter screens that we have going now.

If you randomly make a few new finder windows and then resize them, and then try to run it again, sometimes it doesn't re-size it properly.

Here's the versions of the script I'm working with. You'll see I'm using a variable for the app; ultimately I want to use this on various apps, not just Finder. I'm also setting it up so that it can become a template.

// Soundflow checks number of screens, and screen sizes
sf.ui.screens.invalidate();

// Use 0 for main screen, 1 for second screen etc
var screenNumber = 0;

// I want to replace this with something that recognises the active foreground application, and gets the name/id of the app so that we can manipulate the windows
var app = sf.ui.finder;

let appWindow = app.windows.first;

// Check if there is a window open
if (appWindow.exists) {
    app.menuClick({ menuPath: ['File', 'New Finder Window'] });
    appWindow.elementWaitFor(); 
}

// Bring the active window to the front of other apps
appWindow.elementRaise();

// Define visible screen properties as 'mainScreen' (excluding menu bar)
let mainScreen = sf.ui.screens.allScreens[screenNumber].visibleFrame;

// Whole screen size including menu bar
let entireMainScreen = sf.ui.screens.allScreens[screenNumber].frame;

// Notes:
// mainScreen.w is the same as sf.ui.screens.allScreens[screenNumber].invalidate().visibleFrame.w
// The usable width of your main screen is: ${mainScreen.w} pixels
// mainScreen.h is the same as sf.ui.screens.allScreens[screenNumber].invalidate().visibleFrame.w
// The usable heigh of your main screen is: ${mainScreen.h} pixels
// The app window is ${appWindow.frame.w} pixels wide
// The app window is ${appWindow.frame.h} pixes tall
// The window is at the screen coordinates of: ${appWindow.frame.x}, ${appWindow.frame.y}

// --------------------------------------------
// Quarter-size windows:
// First re-size, then move

// Resize window, make window half the screen height, and half the screen width
// appWindow.windowMove({ size: { x: mainScreen.w / 2, y: mainScreen.h / 2, } });

// Move to top left
// appWindow.windowMove({ position: { x: 0, y: 0, } });

// Move to bottom left
// appWindow.windowMove({ position: { x: 0, y: entireMainScreen.h - appWindow.frame.h, } });

// Move to top right
// appWindow.windowMove({ position: { x: entireMainScreen.w - appWindow.frame.w, y: 0, } });

// Move to bottom right
// appWindow.windowMove({ position: { x: entireMainScreen.w - appWindow.frame.w, y: entireMainScreen.h - appWindow.frame.h, } });

// --------------------------------------------
// Half-size windows:
// First re-size, then move

// Make window full screen height, and half the screen width
appWindow.windowMove({ size: { x: entireMainScreen.w / 2, y: entireMainScreen.h, } });

// Right - not working reliably yet
appWindow.windowMove({ position: { x: entireMainScreen.w - appWindow.frame.w, y: 0, } });

// --------------------------------------------
// Make the window move to the centre of the screen
// appWindow.windowMove({ position: { x: (mainScreen.w / 2) - (appWindow.frame.w / 2) , y: (mainScreen.h / 2)  - (appWindow.frame.h / 2), } });
