I think I figured where the issue is

I placed few rar files in the desktop and it works normal in queue if the destination is the mac

but when i changed the destination to the external harddisk the program gives the "null" error after finishing the first file

same thing if I process it from the External HDD to the desktop.

so

from mac to mac, no isse
from mac to external, problem
from external to mac, problem

So sorry for the bad way to explain things
