# Clearing up Lost & Found data

## What is Lost & Found data?

Sometimes, when deleting files in your account, the whole thing doesn't get deleted completely. For example, when deleting a room, the room itself will get deleted, but metadata like room shape, level lines used, etc. is still retained and orphaned, meaning it's no longer usable, but it's still taking up precious storage space.

## How to clear Lost & Found data

1.  Go to your [Usage & Billing page](https://stage.metareal.com/?app=usage)
2.  In line with the Assets Stats section, click "Lost & Found"
3.  Click "Select All", then "Delete"
4.  Go back to the Summary page under the Usage & Billing page, and you'll see that some of your storage space has freed up again.
