# Feature: #70002 - Make it possible to register own icons for file extensions

See [forge#70002](https://forge.typo3.org/issues/70002)

## Description

The IconRegistry has been extended with a mapping of file extensions.

## Impact

It is now possible to register or overwrite the iconIdentifier for a file extension.

```php
$iconRegistry = GeneralUtility::makeInstance(IconRegistry::class);
$iconRegistry->registerFileExtension('log', 'icon-identifier-for-log-files');
```
