# Managing a project
This page contains essential information for effectively managing your project in HOLOPLOT Control and recommended best practices to ensure your project settings are always up to date.
The Project Library section lets you easily manage the projects available on the controller. To access this section, click **Settings** (located in the top right of the navigation bar). Once inside, you will see a 2-panel layout:
* The left panel shows all projects available in the controller.
* The right panel displays the details of the selected project.

### Adding a project
Click the **Add Project** button in the left panel, then browse for the desired project file and confirm the upload. Please note that only one file can be uploaded at a time.
After adding a project to the Project Library, you can proceed with activation or leave it stored in the controller for later use.
{% hint style="info" %}
Only **.holoplot** files are supported, and HOLOPLOT Plan can read them.
{% endhint %}
### Replacing a project
When a Project with the same ID as an existing one is added to HOLOPLOT Control, the newly added project will replace the existing one. If this new file contains settings, they will overwrite the settings stored in the old file (module pairing, network settings, audio routing, etc).

{% hint style="info" %}
**How do we detect already loaded projects?**\
When generating a project, HOLOPOT Plan assigns a unique identifier. If the user reuploads a project with the same unique identifier, HOLOPLOT Control will detect and prompt the user to override it.
{% endhint %}
#### Downloading a local copy of the project
You can download copies of any project stored in the Controller. To do so, click on the three-dot menu at the top-right of each project container and click **Download Copy.**
{% hint style="success" %}
The **Download Copy of the Project** option is automatically selected to save a local file version on your computer, including module pairing, network settings, audio routings, and/or beam tuning values.
{% endhint %}
#### What information is generated and altered in which software?
| In HOLOPLOT Plan | In HOLOPLOT Control |
| --------------------------------------- | -------------------------------- |
| Position and number of modules & arrays | Network settings |
| Number of presets and preset layers | Module's pairing |
| Beams and beam properties | Audio Input's routing to streams |
| Environmental conditions | Beam's tuning values |
| Audio inputs | |
### Activating a project
To activate a project, you can do it in two ways:
1. On the left panel, click the three-dot menu at the top right of the project container, and then click **Activate**.
2. Select the project container, and then click the Activate button at the top right on the right panel.
The project's activation time depends on the file size.
{% hint style="warning" %}
It is recommended to mute the system before activating a project.
{% endhint %}
Project Activation
{% hint style="info" %}
Only one project can be active at a time.
{% endhint %}
### Deleting a project
Deleting a project is always possible as long as it is inactive. To do so, click on the three-dot menu at the top-right of each project container and click **Delete Project.**
