How do I join two .rar folders?

I don't either, but when using a GUI to open a .rar, after Ark opens the 
folder, you can't always cut and paste the file that results, at least not in 
my computer.  When I can, I do.  When I can't, I go through the hastle of 
opening the .rar each time.  Several wasted steps.

I hope I understand this one well enough to repeat, it is nice to remove the 
intermediate steps.
