Locking files unless linked to it option
While researching how to prevent downloading of proprietary videos and content, I came across a 2015 post discussing a workaround for locking files. The post mentions the need to "Go to Files and choose the option to lock the file unless you link to it." I cannot find such an option. Has this option been removed?
Anyone have a work around for preventing downloading?
