# Handling file uploads

Genie has built-in support for working with file uploads. The collection of uploaded files (as `POST` variables) can be accessed through the `Requests.filespayload` method. Or, we can retrieve the data corresponding to a given file form input by using `Requests.filespayload(key)` -- where `key` is the name of the file input in the form.

In the following snippet we configure two routes in the root of the app (`/`): the first route, handling `GET` requests, displays an upload form. The second route, handling `POST` requests, processes the uploads, generating a file from the uploaded data, saving it, and displaying the file stats.

### Example
