# SmartFTP

SmartFTP is a file transfer app for Windows. Its **S3** protocol connects to Zata, so you can drag and drop files to and from a bucket.

## 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).
* SmartFTP installed — [download SmartFTP](https://www.smartftp.com/en-us/download).

## Connection settings

| Setting                           | Value                                                                                         |
| --------------------------------- | --------------------------------------------------------------------------------------------- |
| Protocol                          | **S3**, with **Custom** in the list below it                                                  |
| Host                              | `idr01.zata.ai` for Indore, `bom01.zata.ai` for Mumbai — no `https://`                        |
| Port                              | `443`                                                                                         |
| Path                              | optional — `/my-bucket` to open one bucket directly. Needed for sub-user keys.                |
| Access Key Id / Secret Access Key | from **Access Keys** in the Zata console — the key must be from the same region as the bucket |

## Set up SmartFTP

#### Open a new connection

Open SmartFTP and start a new connection (**File** → **Connection**, or press `Ctrl+N`).

#### Enter the Zata details

Set **Protocol** to **S3** and the list below it to **Custom**. Enter the **Host**, **Port**, **Access Key Id** and **Secret Access Key**. To open one bucket directly, enter it in **Path**, for example `/my-bucket`. Select **OK**.

#### Browse the bucket

SmartFTP connects and shows your buckets, or the bucket from **Path**.

## Test it

Select **Upload**, or drag a small file into the bucket. Check that it appears in the same bucket in the Zata console under **Buckets**. Then drag it back to a local folder to check that downloads work.

## Troubleshooting

| Problem                                                  | Fix                                                                                          |
| -------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
| Error listing buckets, or access denied at the top level | Your key cannot list all buckets (for example a sub-user key). Set **Path** to `/my-bucket`. |
| Cannot connect                                           | Check that **Host** matches the region of your key and **Port** is `443`.                    |
| Invalid credentials                                      | Copy the keys again from **Access Keys**, without extra spaces.                              |
