# Files
| Path                                                       | What                                                                                                                                                                          |
|------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `~/Library/Application Support/Undertone/Pictures`         | The pictures, as PNGs, named by a fingerprint of what they show and the display's size. A picture is drawn once and reused; one no display has shown for two days is deleted. |
| `~/Library/Application Support/Undertone/Motion`           | With lock screen motion on: each display's loop and settle movies, and `motion.json` naming them for the screen saver.                                                        |
| `~/Library/Screen Savers/Undertone.saver`                  | The screen saver, copied from the app when lock screen motion is turned on, and updated with the app.                                                                         |
| `~/Library/Application Support/Undertone/undertone.lock`   | Keeps a second copy of Undertone from running.                                                                                                                                |
| `~/.config/undertone/config.toml`                          | The [settings](https://mpdreamz.github.io/undertone/reference/configuration), for your dotfiles (under `$XDG_CONFIG_HOME` when that is set).                                  |
| `~/Library/Preferences/io.github.mpdreamz.undertone.plist` | What is showing now, the last shuffle, and pause.                                                                                                                             |

`brew uninstall --zap undertone` removes all of them. A 4K picture with grain is about 10 MB.
