# Storage Architecture

Notebooks are a web-based Jupyter IDE with shared persistent storage for long-term development and inter-notebook collaboration, backed by accelerated compute.

The file manager does **not** represent the full file structure of the notebook. The full file structure of a notebook looks like this:

```
  graph LR
  HOME("~") --> ROOT("/")

  ROOT --> NB("/notebooks")
  ROOT --> DS("/datasets")
  ROOT --> ST("/storage")
  ROOT --> SYS("{ system files }")

  NB --> IDE("{ notebook IDE }")
  DS --> DATA("{ dataset files }")

  ST --> STNB("/notebooks*")
  ST --> TEAM("{ team storage }")

  STNB --> USERNB("{ user notebooks }")

  %% Styling
  classDef highlight fill:#fff3cd,stroke:#f0ad4e,stroke-width:2px;
  class IDE highlight;
```

## Main Components

- **File Manager**: Only contains files available in the Paperspace console. This corresponds to the `/notebooks` directory, and these files persist across notebook sessions.
- **Storage**: Shared [persistent storage](https://docs.digitalocean.com/products/paperspace/notebooks/details/storage-types/index.html.md#persistent-storage) directory accessible to your entire team on a specific cluster. This corresponds to the `/storage` directory, and is a method for sharing data across notebooks and users. For **Private Workspace** teams, other users cannot share the `/storage` volume.
- **Paperspace Datasets**: Team and public datasets that are mountable in the Paperspace console. This is ideal for large amounts of data and for sharing. Public datasets include popular datasets that Paperspace makes available out of the box such as [MNIST](http://yann.lecun.com/exdb/mnist/).

**Warning**: Within the `/notebooks` directory, the folder name `checkpoints` is reserved by Jupyter. Avoid using `checkpoints` as a directory name in order to avoid any unexpected behavior.

To view and keep track of storage utilization, visit the **Storage** tab in your team settings. The amount of free storage accessible to a team is dictated by the Paperspace subscription tier. Any storage over these limits is charged. For more information, see [pricing](https://docs.digitalocean.com/products/paperspace/pricing/index.html.md#paperspace-gradient).
