> Why? In 2017, we rolled out a security update to the system that generates new Unlisted video links. This update included security enhancements that make the links for your Unlisted videos even harder for someone to discover if you haven’t shared the link with them. We’re now making changes to older Unlisted videos that were uploaded before this update took place.
When Google bought Youtube Videos, I followed their directions on the new password, etc.
Something went wrong, and I couldn't delete, or edit my own videos.
They weren't that embarassening, but I used youtube originally as kind of a diary, or todo list.
I tried for awhile to get them off, but failed, and just gave up.
I did reach a human in advertising one day, and she told me, "Those issues are not what they hired he fooor. Try the help boards?". (She brought back memories of certian new college grads, and I realized how difficult it is to talk to a human at Google.)
Anyway--the vids are still up their years later, with people telling me how lousy they are. I just commented on my own videos. Telling people at one time, some uploaders just posted without thinking about clicks.
With respect to storage, there's a provision to delete old videos in the EULA at any time Google chooses. Eventually Google will pull the trigger.
Caching, I'm not so sure, but I'd be surprised if hiding old unlisted videos freed up enough of it to matter. New videos probably dominate cache storage.
