Various examples 

print(application:get("windowTitle"))
print(application:get("documentDirectory"))
print(application:get("temporaryDirectory"))

-- get screen size
screenwidth, screenheight = application:get("screenSize") -- the actual user screen size!
application:set("windowPosition", (screenwidth - myappwidth)/2, (screenheight - myappheight)/2) -- center the app
application:set("windowTitle", "MY TITLE")

-- get the user download folder path
print(application:get("directory", "download")) -- prints C:/Users/xxx/Downloads

File dialog open directory 

--local path = application:get("openDirectoryDialog", "Title|C:/tmp/") -- "title|path" DEPRECATED IN 2022.10
local path = application:get("openDirectoryDialog", "Title", "C:/tmp/") -- "title", "path" NEW WAY
-- win32
local path = application:get("openDirectoryDialog", "Title", "C:\\tmp\\") -- "title", "path" win32 NEW WAY
print(path)

File dialog open file 

print(application:get("openFileDialog","Choisissez un liquide","I:\\","Bidon (*.bdn *.bid);;Fût et Tonneau (*.fut)"))
path = application:get("openFileDialog", "My Title", "c:\\", "Images (*.png *.jpg *.jpeg);;3D (*.obj *.glb *.fbx)"))
print(path) -- on cancel, returns nil for win32 and "" for other systems

-- file dialog to open a file of type .txt or .png
local path = application:get(
--	"openFileDialog", "Title|C:/tmp/|Text (*.txt);; Image (*.png)") -- "title|path|extensions" DEPRECATED IN 2022.10
	"openFileDialog", "Title", "C:/tmp/", "Text (*.txt);; Image (*.png)") -- "title", "path", "extensions" NEW WAY
print(path)

-- file dialogs on win32 should use a delay Timer.delayedCall or Core.asyncCall
--self.tiled_ui.btnBrowse:addEventListener("clicked", self.browse, self) -- instead of this
self.tiled_ui.btnBrowse:addEventListener("clicked", function()
	Core.asyncCall(TheStage.browse, self) -- this
end)

File dialog save file 

-- first we choose the destination
local path = application:get(
--	"saveFileDialog", "Title|C:/tmp/|Text (*.txt);; Image (*.jpg)") -- "title|path|extensions" DEPRECATED IN 2022.10
	"saveFileDialog", "Title", "C:/tmp/", "Text (*.txt);; Image (*.jpg)") -- "title", "path", "extensions" NEW WAY
-- and we save some data to it
if path ~= 0 then
--if path ~= nil then -- for win32
	local srcf = io.open("mytext.txt", "rb")
	local dstf = io.open(path, "wb")
	local size = 2^13 -- good buffer size (8K)
	while true do local block = srcf:read(size) if not block then break end dstf:write(block) end
	srcf:close()
	dstf:close()
end

Path File Exists 

-- Path File Exists for Windows 64
-- tests folder path (nil=doesn't exist, 1=exists)
if application:get("pathfileexists", application:get("directory", "pictures").."/Folder01") == nil then
	application:set("mkDir", application:get("directory", "pictures"), "Folder01")
	application:set("mkDir", application:get("directory", "pictures").."/Folder01", "subfolder01")
	application:set("mkDir", application:get("directory", "pictures").."/Folder01", "subfolder02")
end

-- Path File Exists for win32
-- tests folder path (nil=doesn't exist, 1=exists)
if application:get("pathfileexists", application:get("directory", "pictures").."\\Folder01") == nil then
	-- creates it
	application:set("mkDir", application:get("directory", "pictures").."\\Folder01")
end
