EDIT: All installed new app have an ID or that called sandbox. is there possible way to copy file from root to sandbox app documents? Here what i'm trying to do... root: "Applications/MyApp.app/Data.txt" Copy Data.txt file to this path will be fine. Home: "/Applications/7AC2295E-2775-41EA-B017-AB4048A09F0C*/Document/" Next time "7AC2295E-2775-41EA-B017-AB4048A09F0C*" path will change after delete and install it again. So now how to get that path if that number-number-number-number sandbox is changed? help would be appreciated.
