Copy file and move file node help

Hello, so i wanted someone to explain the “copy file” and “move file” nodes to me.
What i dont get is the dest file string and the source file string. What do i write in there?
i have done a whole bunch of combinations and it keeps failing.
Does it copy a file to a new location or just copy? How would i paste it to new location?
Do i use the move node once copied?
If anyone could give me a small example that would be amazing and i could get back to coding.

You must enter root path including asset name for both source (copy from) and destiation (copy to)
Ex: t:/UE5/Game/Content/Developer/cube.uasset

But I got a problem with source control which not mark for add on depot but mark for branch
