Remove processed files and cached images stored by TYPO3 to free up disk space.

TYPO3 stores processed files (such as image variants and thumbnails) in a dedicated directory that can grow quickly over time.
Use this action to delete these files. Afterward, clear the cache database tables to ensure consistency.

The File Abstraction Layer (FAL) also keeps database records for processed files. If image processing settings have changed (see System → Settings → Configure Installation-Wide Options → [GFX]), removing processed files forces them to be regenerated with the updated configuration.
