If i click on a file from the internet search that is just a par2 file set and I don't have the any files associated with the the par set, newsbin will then download add the par2 files. Creating folders with nothing but par2 files. While I can see this may be useful from time to time. I does have the tendency to take up disk space. Maybe an added option, but have the option that Newsbin Loads the par-set into the download list but skip downloading it if there are no files for it to fix.
