# DAR Packages

The **DARs** page manages Daml Archive (DAR) files on this validator's participant node.

<div data-with-frame="true"><figure><img src="/files/kvnKkbpMGo6wClVqz8w9" alt=""><figcaption></figcaption></figure></div>

DAR files contain compiled Daml smart contract code. A package must be uploaded to a participant before contracts from that package can be used on the ledger.

***

### Uploading a DAR

Use the drag-and-drop upload area at the top of the page or click to choose the DAR from your file system. Multiple DAR files can be uploaded in a single operation.
