# Filelog (Deprecated)

{% hint style="info" %}
**NOTE**

This source has been deprecated and replaced with a new [Filelog](/integrations/sources/filelog.md) source. While it will continue to function, it will no longer receive any enhancements and you should migrate to the new source.
{% endhint %}

{% hint style="danger" %}
**WARNING**

This source offers a delete\_after\_read option that can be hazardous. When this option is combined with file globbing, it will delete every file that matches the globbing pattern. Use with caution and care.
