# Domino File System

This topic describes the filesystem structure you will find when you use a Domino File System (DFS) project.

The filesystem root (`/`) contains the following directories.

```console theme={null}
/
├── bin
├── boot
├── dev
├── domino  # Contains the datasets directory.
├── etc
├── home
├── lib
├── lib32
├── lib64
├── media
├── mnt     # Default working directory.
├── opt
├── proc
├── root
├── run
├── sbin
├── scripts
├── srv
├── sys
├── tmp
├── usr
└── var
```

## Domino working directory

When you start a Run from a DFS project, Domino loads all the files needed for your project into the `domino` working directory.

By default, your working directory is `/mnt`. The folders and files from your project will be in that directory.

If your project is set up to [import another project](/cloud/platform-capabilities/core-concepts/projects/collaborate-on-projects/export-import-project), your working directory is `/mnt/<project-owner-username>/<project-name>`.

A dataset volume is mounted as `/domino/datasets/local/<name>` for Datasets in your home project in DFS. See [Dataset paths in DFS projects](/cloud/platform-capabilities/core-concepts/data/datasets/use-datasets-and-snapshots#dataset-paths-in-dfs-projects) for more information.

<Note>
  Domino sets the `DOMINO_WORKING_DIR` environment variable for all Runs. This variable contains the path to your working directory.
</Note>

In addition to your project files, the following files and folders are stored in the working directory:

```console theme={null}
DOMINO_WORKING_DIR/
├── ipynb_checkpoints   # Contains the auto-saved Jupyter states.
├── results             # Contains your generated results.
    └── stdout.txt      # Tail of the console output from your Run.
├── requirements.txt    # Optional: Specifies Python package dependencies.
├── .dominoresults      # Determines which files are rendered as results.
├── .dominoignore       # Contains file patterns for Domino to ignore.
├── .dominokeep         # Prevents directory removal of empty directory.
├── dominostats.json    # Values shown in the Jobs dashboard.
├── email.html          # Controls the formatting of notification emails.
├── .noLock             # Solves "too many open files" messages.
├── app.sh              # Contains app-launching code for Domino Apps.
├── domino.log          # Contains CLI logs for local CLI projects only.
└── .domino.vmoptions   # Contains proxy settings for local CLI projects only.
```
