# Accessing key-based cache archives

You can access your cache archives separately, without running a build. This allows you to keep track of several things:

- What cache keys are associated with different cache archives.
- How much storage space is taken up by your cache archives.
- When each cache archive is due to expire.

In addition, you can download any cache archive - if it hasn't expired yet -, you can copy the cache keys, and you can delete archives.

To access your archives:

1. 1. Open your project on Bitrise with a user that has the **Admin** [role on the project](/bitrise-platform/projects/roles-and-permissions-for-bitrise-ci), or a [custom role](/bitrise-platform/workspaces/collaboration-and-permissions-in-workspaces/custom-roles/custom-roles-overview) with the **Edit workflows** permission.
1. On the main page of the project, click on the **Project settings** button.
1. On the left side, select **Dependency cache**.
1. Click the actions menu next to a cache archive, then select one of the following:

   - **Copy key** to copy the cache key.
   - **Download** to download the cache archive.
   - **Delete** to delete the cache archive.

:::note
Cache archives are compressed with [Zstandard](https://github.com/facebook/zstd). To decompress a downloaded archive, install `zstd`, then run `zstd -d cache.tzst`.
