Hey there, author here.<p>I have an image library of around ~15,000 RAW photo images, which I wanted to organize. After having tried several approaches over the years (organizing them in folders by topic, by year, or some mix of the two...) I gave up and went to build a solution that scales better.<p>ciid is a CLI utility, which you can use to rename image files, so that you can fearlessly merge folders without having to worry about duplicate file names.<p>The derived identifiers are structured in such a way that if you sort them alphabetically, the images will also be sorted chronologically. Additionally, the identifier can later be used to verify the integrity of the image.<p>If you have any questions, I'd be happy to answer.
