# Get file info

A query that returns the current state of a file. Queries do not change the state of the file or require network consensus. The information is returned from a single node processing the query.

**Query Fees**

* Please see the transaction and query [fees](https://dev.uniultra.xyz/docs/networks/mainnet/fees#transaction-and-query-fees) table for the base transaction fee
* Please use the [Hedera fee estimator](https://hedera.com/fees) to estimate your query fee cost

```

{% endtab %}

{% tab title="JavaScript" %}

```javascript

getInfo, err := query.Execute(client)

fmt.Println(getInfo)
```

{% endtab %}
