# Deprecation: #85445 - TemplateService->getFileName

See [forge#85445](https://forge.typo3.org/issues/85445)

## Description

The PHP method `TYPO3\CMS\Core\TypoScript\TemplateService->getFileName()` has been marked as deprecated, as
it is technically extracted into separate functionality with modern architecture throwing PHP Exceptions when
a file name is invalid.

Along with the method the public property `$fileCache` has been marked as deprecated, which acted as a simple first-level
in-memory cache.

## Impact

Calling the method directly or accessing the public property will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

Any TYPO3 installation dealing with PHP code in Frontend (e.g. `$TSFE->tmpl->getFileName()`).

## Migration

Use `TYPO3\CMS\Frontend\Resource\FilePathSanitizer->sanitize($filePath)` instead.
