//! Opens files and folders in the desktop's own apps.
//!
//! egui's `Context::open_url` hands every URL to the web browser, `file://`
//! ones included, so "Open skins folder" through it shows the folder in
//! Firefox rather than the file manager. [`path`] asks the desktop instead:
//! `xdg-open` on Linux and the BSDs, `open` on macOS and `explorer` on
//! Windows. Web links still belong to `open_url`.

/// Opens `path` in the desktop's app for it: a folder in the file manager, an
/// image in the image viewer. Returns once the opener has started; it reports
/// an error only if the opener couldn't be run.
