I'm a photographer and I have a recurring client who I've been shooting for since 2020.
During this time I have put all the pics for them in a folder with a "master" shared link, and in specific occasions I have shared links to subfolders as well.
Links have been passed around too, so who knows how many people have access to these pictures.
Now they want to start fresh, delete all access links including subfolders and have only one person have access to the link to the main folder.
Which is the best procedure for this?
