In order to efficiently manage files in the media folder (upload/move/delete many files at once) it would be very convenient to be able to use an ftp-client. Is there anything I can do so that I will have full access via ftp in the media folder?
Set permissions in dmode and fmode config settings. Maybe use the setgid bit as described at
