Retrieves the whole command line 

-- myapp.exe -param1 -param2
application:get("commandLine")

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!
myappleft, myapptop, myappright, myappbot = application:getLogicalBounds()
myappwidth, myappheight = myappright - myappleft, myappbot - myapptop
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"
local path = application:get("openDirectoryDialog", "Title", "c:\\tmp\\") -- "title", "path" win32
print(path) -- on cancel, returns nil for win32 and "" for other systems

File dialog open file 

local path = application:get("openFileDialog", "My Title", "c:\\", "Images (*.png *.jp*g);; 3D (*.obj *.fbx)")
print(path) -- on cancel, returns nil for win32 and "" for other systems

-- file dialogs on win32 should use a delay Timer.delayedCall or Core.asyncCall
self.tiled_ui.btnBrowse:addEventListener("clicked", function()
	Core.asyncCall(self.browse, self)
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"
-- and we save some data to it
if path ~= "" then -- on cancel, returns nil for win32 and "" for other systems
	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
	-- create it
	application:set("mkDir", application:get("directory", "pictures").."\\Folder01")
