//! This example demonstrates picking of multiple file paths at once.
//!
//! Note that picking a file path does not work on wasm, if you want cross
//! platform solution including wasm, you need to pick+load at once which is
//! provided with `load_multiple_files` instead of `pick_multiple_file_paths`.
//! See the example `load_multiple.rs` for that.
