# Breaking: #101647 - Unused graphical assets removed from EXT:backend {#breaking-101647-1691669710}

See [forge#101647](https://forge.typo3.org/issues/101647)

## Description {#description}

The TYPO3 system extension "backend" accumulated many graphical assets over the
years that became unused piece by piece.

The following icons have been removed from the Icon Registry:

-   `status-edit-read-only`
-   `warning-in-use`
-   `warning-lock`

The following assets have been removed from the directory `EXT:backend/Resources/Public/Images/`:

-   `FormFieldWizard/wizard_forms.gif`
-   `clear.gif`
-   `filetree-folder-default.png`
-   `filetree-folder-opened.png`
-   `Logo.png`
-   `pages.gif`
-   `tt_content.gif`

## Impact {#impact}

Calling any of the removed icons from the Icon Registry will render the default
icon. Accessing any of the removed files directly will lead to a 404 error.

## Affected installations {#affected-installations}

All extensions using the removed icons and assets are affected.

## Migration {#migration}

No direct migration is available.
