The MakePath function, particularly:
snprintf(path, length, "%s/time-%02x/%02x/%02x/%04x-%04x",
innconf->patharticles, class,
(now >> 16) & 0xff, (now >> 8) & 0xff, seqnum,
(now & 0xff) | ((now >> 16 & 0xff00)));
and particularly the (now >> 8) & 0xff part, which changes directories
every 256 seconds, or a little over four minutes. If you want to change
that, the easiest is probably to change it to:
snprintf(path, length, "%s/time-%02x/%02x/%02x/%04x-%04x",
innconf->patharticles, class,
(now >> 15) & 0xff, (now >> 7) & 0xff, seqnum,
(now & 0xff) | ((now >> 16 & 0xff00)));
which will change directories every 64 seconds.
