# Deprecation: #95077 - FileDump CheckFileAccess hook

See [forge#95077](https://forge.typo3.org/issues/95077)

## Description

The TYPO3 hook `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['FileDumpEID.php']['checkFileAccess']`
which is executed in the `\TYPO3\CMS\Core\Controller\FileDumpController` class, enabling third-party
code to perform additional access / security checks before dumping the requested
file, has been marked as deprecated.

The accompanied PHP interface for the hook
`\TYPO3\CMS\Core\Resource\Hook\FileDumpEIDHookInterface` has been marked
as deprecated as well.

## Impact

If a hook is registered in a TYPO3 installation, a PHP `E_USER_DEPRECATED` error is triggered.
The extension scanner also detects any usage
of the deprecated interface as strong, and the definition of the
hook as weak match.

## Affected Installations

TYPO3 installations with custom extensions using this hook.

## Migration

Migrate to the newly introduced `\TYPO3\CMS\Core\Resource\Event\ModifyFileDumpEvent` PSR-14 event.
