# Save and back up your work

Name a project, keep a backup as a .kerf file, recover a draft, and what to do when the browser cannot save.

Your work saves itself in this browser after each change. The browser is not a backup: if you clear its data, your projects are gone. Keep a .kerf file of each project that matters.

## Name a project

Until you name it, a project is a draft and the toolbar shows **Draft**.

1. Press Ctrl+S (⌘S on a Mac).
2. In **Name**, type a name.
3. Select **Also download a .kerf file**.
4. Click **Save**.

The project is now in **File ▸ All projects…**. Your browser then asks where to save the .kerf file, or downloads it. To put the assistant conversation in the file, also select **Include the assistant conversation in the file**.

## Back up a saved project

1. Select **File ▸ Download .kerf…**.
2. Click **Download**, and select where to save the file if your browser asks.

A .kerf file holds the whole project: parts, materials, finishes, parameters and imported models. Keep it with your other files, or send it to another person.

## Open a .kerf file

1. Select **File ▸ Open file…**.
2. Select the file.

The file opens as a new saved project. If you already have the same project, your copy does not change. To add the file to the open project instead, use **File ▸ Insert from file…**.

## Recover a draft

KerfCraft keeps a draft until you save it or discard it. If you have drafts from an earlier session, a badge next to **File** shows how many.

1. Click the badge, or select **File ▸ All projects…**.
2. Under **Unsaved drafts**, click the **Recover** icon on the row of the draft.
3. Press Ctrl+S (⌘S on a Mac) and give it a name.

To delete a draft, click the **Discard** icon on its row. You cannot undo this. Hold the pointer on an icon to see its name.

## If the toolbar shows "⚠ Not saved"

Your latest changes are only in this tab. If the message says **storage full**, the browser has no more space.

1. Do not close the tab.
2. Select **File ▸ Import / Export…**.
3. On the **Export** tab, select **KerfCraft package (.kerf)** and click **Export…**.
4. In **File ▸ All projects…**, delete projects or drafts that you do not need.
5. Press Ctrl+S (⌘S on a Mac).

The export holds the design as it is in the tab, so you lose nothing.
