# Local CSV
:::danger
This destination is meant to be used on a local workstation and won't work on Kubernetes
:::
## Overview
This destination writes data to a directory on the _local_ filesystem on the host running Airbyte. By default, data is written to `/tmp/airbyte_local`. To change this location, modify the `LOCAL_ROOT` environment variable for Airbyte.
:::caution
Please make sure that Docker Desktop has access to `/tmp` (and `/private` on a MacOS, as /tmp has a symlink that points to /private. It will not work otherwise). You allow it with "File sharing" in `Settings -> Resources -> File sharing -> add the one or two above folder` and hit the "Apply & restart" button.

### Sync Overview
#### Output schema
Each stream will be output into its own file. Each file will contain 3 columns:
- `_airbyte_ab_id`: a uuid assigned by Airbyte to each event that is processed.
- `_airbyte_emitted_at`: a timestamp representing when the event was pulled from the data source.
- `_airbyte_data`: a json blob representing with the event data.
#### Features
| Feature | Supported | |
| :----------------------------- | :-------- | :-- |
| Full Refresh Sync | Yes | |
| Incremental - Append Sync | Yes | |
| Incremental - Append + Deduped | No | |
| Namespaces | No | |
#### Performance considerations
This integration will be constrained by the speed at which your filesystem accepts writes.
## Getting Started
The `destination_path` will always start with `/local` whether it is specified by the user or not. Any directory nesting within local will be mapped onto the local mount.
By default, the `LOCAL_ROOT` env variable in the `.env` file is set `/tmp/airbyte_local`.
The local mount is mounted by Docker onto `LOCAL_ROOT`. This means the `/local` is substituted by `/tmp/airbyte_local` by default.
### Example:
- If `destination_path` is set to `/local/cars/models`
- the local mount is using the `/tmp/airbyte_local` default
- then all data will be written to `/tmp/airbyte_local/cars/models` directory.
## Access Replicated Data Files
If your Airbyte instance is running on the same computer that you are navigating with, you can open your browser and enter [file:///tmp/airbyte_local](file:///tmp/airbyte_local) to look at the replicated data locally. If the first approach fails or if your Airbyte instance is running on a remote server, follow the following steps to access the replicated files:
1. Access the scheduler container using `docker exec -it airbyte-server bash`
2. Navigate to the default local mount using `cd /tmp/airbyte_local`
3. Navigate to the replicated file directory you specified when you created the destination, using `cd /{destination_path}`
4. List files containing the replicated data using `ls`
5. Execute `cat {filename}` to display the data in a particular file
You can also copy the output file to your host machine, the following command will copy the file to the current working directory you are using:
```text
docker cp airbyte-server:/tmp/airbyte_local/{destination_path}/{filename}.csv .
```
Note: If you are running Airbyte on Windows with Docker backed by WSL2, you have to use similar step as above or refer to this [link](/integrations/locating-files-local-destination.md) for an alternative approach.
