Amongst other things, fsck_ffs(8) looks for inodes not mentioned in
any directory, i.e. files that are orphans. fsck_ffs links those files
into the lost+found dir, using the inode number for a name.
Try to figure the contents of the file, using e.g. file(1) or
hexdump(1). On success, just move the files to the right place with
the right name. Often you'll find that those files are not longer
useful, in that case just remove them from lost+found.
