FAL Duplicate Checker
=====================

[](#fal-duplicate-checker)

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
------------

[](#requirements)

- TYPO3 13.4 or 14.x
- PHP 8.2+

Installation
------------

[](#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
------------

[](#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.

License
-------

[](#license)

GPL-2.0-or-later — see [LICENSE](LICENSE).
