Hello !  
I’m building a multi page app with dash, and in one of them I’m using a file upload. How can I use the uploaded file in all the other pages ?

Thanks !

Hi @antonin45 and welcome to the Dash community 🙂

If your files are small, you can use a `dcc.Store` component. You can find an example here:

> **[dash-multi-page-app-demos/multi\_page\_store at main ·...](https://github.com/AnnMarieW/dash-multi-page-app-demos/tree/main/multi_page_store)**
>
> main/multi\_page\_store

Otherwise, you could use a database.
