ownership and sharing for pre-existing files and folders

thanks for the reply and clarification

You should be able to simply set the permissions once (as you already have done). There do appear to be some oddities with the built-in media share. Maybe try a test with a new built-from-scratch folder??

my tests so far show that files are locked to any user who didn't copy them to the picture folder - regardless of whether i enable "automatic permissions" (i have no idea what that or ACL changes actually meansthough!)

my current settings for Media share are:

Auto Permissions [unchecked]

Folder Creation Group Rights: Read/Write
Folder Creation EveryOne Rights: Read/Write
File Creation Group Rights: Read/Write
File Creation Everyone Rights: Read/Write

tonight i'll try making a new share from scratch and see if that somehow effects the results.

at the risk of beating a dead horse - any written guides or documentation anywhere???????????
