PDF and image flipbooks are built from files. When you choose a PDF or images while creating a flipbook, each file comes from one of three places.

## Three places a file can live

|                                    | Shopify Files                                       | Managed storage                                | A link                        |
| ---------------------------------- | --------------------------------------------------- | ---------------------------------------------- | ----------------------------- |
| Where it’s stored                  | Your store’s Files                                  | With the app, separate from your store’s Files | Your own website or file host |
| Largest file                       | 20 MB                                               | 100 MB                                         | Up to your host               |
| How it gets there                  | Upload it in the app, or it’s already in your store | Upload it in the app                           | Paste the link in the app     |
| Where you manage it                | **Content → Files** in your Shopify admin           | The app’s **Assets** page                      | Your host                     |
| Protected while a flipbook uses it | No                                                  | Yes                                            | No                            |

Uploads go to Shopify Files unless you choose Managed storage. A file over 20 MB goes to Managed storage automatically. In the **Your files** list, Managed storage files have a **Managed storage** badge, pasted links have a **Link** badge, and Shopify files have no badge.

> **Keep the files your flipbooks use**
>
> A flipbook loads its PDF or images from where they are stored. If you delete a file from Shopify Files, or move or delete a linked file on your host, the flipbook breaks. Nothing stops you deleting a Shopify file that a flipbook uses. Managed storage files can’t be deleted while a flipbook uses them.

## Good to know

- Deleting a flipbook doesn’t delete its files. You can tidy up Managed storage on the [Assets page](https://docs.neoflipbook.com/files/assets-page/).
- Anyone who has a file’s address can open it, so don’t use files you need to keep private.
- Product catalogs don’t use these files. Product images come from your products, and a custom cover image is saved to Shopify Files.
