Thank you, dinos,
I know about this command, but it doesn't check directory existence. Also, I use ActiveX to determine the absolute path to the MoI folder.
Just downloaded MoI (Mac version). I think it's no need to determine it, because that path is fixed (c:\moi). It's very good news for me.
I will make Mac version of this script today, but I need to turn off some checks. Also I need to block Delete/Rename function. I'll think about it later.
