then @file{hdr/} files are automatically created for every ordinary

header of the corresponding packet. It will be automatically created

There is a hack: you can create more dense @file{hdr/} allocation by
-removing all @file{hdr/} files and then running @command{nncp-stat},

that will recreate them. In many cases many @file{hdr/} files will be
allocated more or less linearly on the disk, decreasing listing time
even more.
