# Deprecation: #90686 - Model FileMount {#deprecation-90686}

See [forge#90686](https://forge.typo3.org/issues/90686)

## Description {#description}

The class `\TYPO3\CMS\Extbase\Domain\Model\FileMount` has been marked as deprecated.

The `FileMount` is an internal class which never really had any functionality
besides being an Extbase model for the database table `sys_filemounts`. Therefore
and in order to streamline the codebase of Extbase, the class `FileMount` will be removed with TYPO3 11.0.

## Impact {#impact}

Using `FileMount` will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations {#affected-installations}

Any TYPO3 installation with a third-party extension using the model.

## Migration {#migration}

Copy the class and mapping to your own extension and adopt the usages.
