[Ci-users] artifacts.ci.centos.org - delete particular directory

Hello,

Is there a way how to easily delete particular directory in artifacts.ci?

I'm aware of `rsync --delete ...` command but this will need to download 
whole content from artifacts.ci (or at least content of parent 
directory), delete the particular directory and rsync it back.
Is there some easier way, how to cleanup some unused directories?

Or is there already some other method to access artifacts.ci beside 
rsync? (I've spotted some short relevant discussion on this mailing list 
one year back, but I'm not aware of any result.)

Thanks,
Daniel
