# Removing Sub-Assets

## Drag and drop

To remove one or more sub-assets from an asset, simply select all the assets you want to remove, and drag them into an empty space in the Project window (or directly to another folder).

Just like that, the sub-assets will be extracted and become individual main assets.

Extracting a sub-asset like this is immediate, and doesn't present a confirmation window.

**Preserving References**

When adding a sub-asset using drag and drop, normally the references to the original asset will break. SubAssets Toolbox has a way to prevent this, and you can find more about it in [Patch References](https://tools.continis.io/subassets-toolbox/editor-workflows/patch-references).

## Deleting sub-assets

If you want to delete a sub-asset and not just unparent it, you can also select it and use **right-click > Delete SubAsset(s)**.

Alternatively, you can hit Ctrl+Backspace (Windows) or Cmd+Backspace (Mac) as a shorcut.

When deleting a sub-asset this way, Unity will present this warning in the console:

> The operation "Delete" cannot be executed because the selection is a root folder.

You can safely ignore it.
