H'lo Richard,

The purpose of "bf_compact dir" is to compact the wordlist(s) in
directory "dir".  For database security, a new directory is created to
hold the newly compacted wordlists.  Once the compacting is done, the
original directory, i.e. "dir", is renamed to "dir.old" and the new
directory is renamed to "dir".  A special check is included for file
DB_CONFIG and it's copied to the new directory.  Other files in "dir"
are left unchanged, hence end up in "dir.old".

Given the directory renaming, "bf_compact ." is problematical :-<

HTH,
