When you move a file, check if the parent inode number is equal to the file's 'true parent' inode number, and if so, update the 'true parent' pointer. And do a similar thing when you delete. -- Hubert Chan <[EMAIL PROTECTED]> - http://www.uhoreg.ca/ PGP/GnuPG key: 1024D/124B61FA Fingerprint: 96C5 012F 5F74 A5F7 1FF7 5291 AF29 C719 124B 61FA Key available at wwwkeys.pgp.net.
