Sometimes Newsbin auto-creates directories with very long file names, usually of the form <some long string>..<some long string again>.
On some versions of windows you can turn off the long file name limit, but on others it can't be disabled. The long file names are a problem for those versions of windows, causing various of autopar and autorar to fail.
It would be great if Newsbin could implement some method for keeping the names shorter when they get too long.
