How to hide resource files in an application and release them as needed?

How to hide resource files in an application and release them as needed? For example, to implement the function of creating a project, the project file template needs to be released to a specified directory.

For a template that should be written only when the user creates a project, embed its bytes in your Rust binary and write them to the chosen destination then:

fn create_project(destination: &std::path::Path) -> std::io::Result<()> {
    std::fs::create_dir_all(destination)?;
    std::fs::write(
        destination.join("project.template"),
        include_bytes!("../templates/project.template"),
    )?;
    Ok(())
}

The example assumes this code is in src-tauri/src/ and the source template is at src-tauri/templates/project.template. include_bytes! places the file bytes in the executable, so there is no separate template file to copy from the installed app. The destination must be one the user selected or your app is allowed to write.

If you are comfortable shipping the template as a separate app resource, Tauri also supports bundle.resources and resource-path resolution. A bundled resource is available to the installed app before project creation; it is not concealed. Neither approach protects a secret from someone who has the app binary, so do not put credentials in the template.
