# Collections

## My Collection

In the **My Collection** tab, DAR packages and UI packages can be uploaded to the console. These can then be uploaded to participants or deployed as applications respectively.

### DAR Collections

When a Daml project is compiled, the compiler produces a Daml archive. These are platform-independent packages of compiled Daml code that can be uploaded to a Daml ledger or imported in other Daml projects. Daml archives have a `.dar` file ending.

{% hint style="info" %}
DAR files can be uploaded from the user's local computer, or obtained from the Canton Package Manager (CPM).

To read about CPM interaction, see the Canton Package Manager section of this guide.
{% endhint %}

#### Upload a DAR file

To upload a DAR file, go to the **Collections** tab and click **Upload DAR File** to open a side window.

### UI Collections

The UI Collections feature of Catalyst allows you to provide a frontend for your app by publishing files exposed by HTTPS over a ledger-specific subdomain.

{% hint style="warning" %}
UI Collections must be uploaded to the console and deployed in the form of `.zip` files. The `.zip` should contain a single root directory, and the contents of that directory should contain an `index.html` along with the rest of the resources for your UI.
{% endhint %}

To upload a UI file, go to the **Collections** tab and click **Upload UI File** to open a side window.
