Ii can copy files when it crated -scan- to other secured folder but when some files are deleted form non secured folder - i must copy all the secured folder to unsecured one(as i could not know which file is deleted ) - thus if users continue to delete some files i must repeat this - many users (about 150 users and many files f(for one year thay may be over 100.000 images) ??
also when to copy files to other secured folder at creation time -(this done by user so it must have the access to that secured folder - for one have known of the domain he can find this secured folder and delete files on it
or
every period i open unsecured folder ,copy the new files -recent date- to secured folder - cause extra work required from me
