26 * Unityed Media is a Samba VFS module that allows multiple AVID
27 * clients to share media.
29 * Add this module to the vfs objects option in your Samba share
35 * vfs objects = unityed_media
38 * It is recommended that you separate out Samba shares for Mac
39 * and Windows clients, and add the following options to the shares
40 * for Windows clients (NOTE: replace @ with *):
42 * veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
43 * delete veto files = yes
45 * This prevents hidden files from Mac clients interfering with Windows
46 * clients. If you find any more problem hidden files then add them to
50 * This module is designed to work with AVID editing applications that
51 * look in the Avid MediaFiles or OMFI MediaFiles directory for media.
52 * It is not designed to work as expected in all circumstances for
