README
A TYPO3 backend extension that detects duplicate files in FAL (sys_file) by comparing SHA1 hashes and displays a warning in the backend file info view.
Requirements
- TYPO3 13.4 or 14.x
- PHP 8.2+
Installation
composer require mfd/fal-duplicate-checker
No additional configuration is required. The extension registers its page TSconfig and backend route override automatically on activation.
How it works
When a backend user opens the file information view (e.g. via the File List module → right-click → Info), the extension queries sys_file for other records that share the same SHA1 hash as the currently viewed file. If any are found, a warning infobox is shown listing the paths of all duplicate files.
Duplicate detection relies on the sha1 column already maintained by the TYPO3 FAL indexer — no additional indexing or scheduler tasks are needed.
