Is this the new format for the download directory

[Brian Keener]

I was just reviewing my download directory and cleaning up old archives and I 
discovered this folder:

ftp%3a%2f%2fmirrors.rcn.net%2fmirrors%2fsources.redhat.com%2fcygwin 

in my download local directory.  Within my download directory I already had a 
contrib and latest folder and now I see this new folder and in looking in it I 
find a setup.ini and another latest folder. 

several questions pop up from this observation:

1) are my contrib and latest  folders in my  local directory no longer 
necessary and
2) does the above new folder (which apparently relates to a mirror) mean I will 
have a folder like this for every possible mirror I ever use :-( ( I really 
hope not )
3) is a folder named this way really necessary.
