Opens a folder (windows 10)
if application:getDeviceInfo() == "Windows" then
local lfs = require "lfs"
-- go to user/pictures folder
lfs.chdir(application:get("directory", "pictures"))
-- check if "my_new_folder" directory exists in user/pictures folder
local islfsdir = lfs.chdir(lfs.currentdir().."\\".."my_new_folder")
if not islfsdir then
-- if doesn't exist then create it and go to it
lfs.mkdir(lfs.currentdir().."\\".."my_new_folder")
lfs.chdir(lfs.currentdir().."\\".."my_new_folder")
end
end
-- opens a window of the current lfs dir
os.execute("start "..lfs.currentdir())
Or if your path contains spaces

--local path = "H:/ShdowPLAY/TMP/Mafia Definitive Edition" -- same
os.execute("start \"\" \"" .. path .. "\"")
