# ExpanDrive

ExpanDrive mounts Zata as a network drive on Windows and macOS, so you can open your buckets from File Explorer or Finder. It connects with its **Amazon S3** connection type. Prefer video? [Watch the setup video](https://youtu.be/63QTHThuyuY).

## Before you start

* A bucket — see [Create a bucket](/buckets/create-a-bucket).
* An access key from the same region as the bucket — see [Access keys](/access/access-keys).
* ExpanDrive installed — [download ExpanDrive](https://www.expandrive.com/download).

| ----------------------- | --------------------------------------------------------------------------------------------- |
| Connection type         | **Amazon S3**                                                                                 |
| Server                  | `idr01.zata.ai` for Indore, `bom01.zata.ai` for Mumbai                                        |
| Access Key / Secret Key | from **Access Keys** in the Zata console — the key must be from the same region as the bucket |
| Region                  | optional — leave it empty or use `us-east-1`                                                  |
| Bucket name             | optional — your bucket, to open one bucket only. Needed for sub-user keys.                    |

## Set up ExpanDrive

#### Add a connection

Open ExpanDrive, select **New Connection** and choose **Amazon S3**.

#### Enter the Zata details

Enter the **Server**, **Access Key** and **Secret Key**. Give the connection a **Nickname**, for example `Zata`. Leave **Bucket name** empty to see all your buckets. On Windows, pick a **Drive Letter** and keep **Automatically Mount as Drive** ticked. Select **Save**.

#### Open your buckets

The connection appears under **CONNECTIONS** with your buckets. Zata is now also a drive in File Explorer or Finder.

## Test it

Copy a small file onto the new drive. Check that it appears in the bucket in the Zata console under **Buckets**. Then copy it back to a local folder and open it.

## Troubleshooting

| Problem                              | Fix                                                                                              |
| ------------------------------------ | ------------------------------------------------------------------------------------------------ |
| Cannot connect                       | Check that **Server** matches the region of your key and bucket.                                 |
| Access denied or invalid credentials | Copy the keys again from **Access Keys**, without extra spaces, and make sure the key is active. |
| No buckets shown                     | Your key cannot list buckets, for example a sub-user key. Enter the bucket in **Bucket name**.   |
