File-system based routing
File-system-based routing is a routing approach in which an application's files and directories determine its externally accessible routes and associated handlers or components.

File-based routing is a routing technique in which filesystem paths and files determine application URL routes.
- How it is used
- Connects dashboard links to file-specific pages through folder-defined URLs.
- How deep it goes
- Demonstrates folder and link implementation, while deferring broader routing behavior beyond nested routes, layouts, and error handling.
- Examples
- Uses an app-directory route, a bracketed id folder, UUID-based URLs, and clickable uploaded filenames.
- What you can do after
- Build it by creating a route folder, adding a page file, and linking records to URLs containing their identifiers.

A routing approach in which an application's file and folder structure determines its routes and rendered components.
- How it is used
- Maps Next.js application folders and files to URL routes, rendered pages, dynamic segments, and shared layouts.
- How deep it goes
- Explains route mapping, dynamic params, project directories, and nested layouts, but does not cover deployment or testing.
- Examples
- Uses root, blog, and dynamic blog-post paths plus root and nested layout structures.
- What you can do after
- Build routes by arranging Next.js app folders, page.js files, dynamic segments, and layout.js wrappers.
