# Execute Command Async

| ## Step Details |
| --- |
| **Introduced in Version** | 4.0.0 |
| **Last Modified in Version** | 7.12.0 |
| **Location** | Flow Management |

The **Execute Command Async** step allows commands to be executed from a Batch file asynchronously. The step is similar to the [Execute Command](/step-library/docs/execute-command) step with a key difference being that the step will run the command asynchronously from the Flow.

---

## Properties

#### Setup

| Property | Description | Data Type |
| --- | --- | --- |
| Command | The absolute file path to the batch file | String |
| ParameterString | Optional setting used to pass parameters used by the command file | Int32 |
| Get Command and Arguments from Flow | Retrieves the inputs for Command and ParameterString through the Flow | Boolean |

## Common Errors

### Could not execute command

A standard error when utilizing the step would be having an incomplete file path to the command file. Ensure that the full file path to the command file is complete and includes the file extension.

#### Exception Message:
