Copy Files/Update all: I will never understand it

Hello again,

I have two folders, source and dest, and just want to update all older files in dest and add the non existing ones to dest. What must I do that no annoying dialog pops up?

Many thanks and greetings

Try this command:

Copy WHENEXISTS=replacenewer

Assuming that by "annoying dialog" you mean the Replace File dialog and not something else.
