# Read File

The Read File tool enables the model to access and read text-based files from three distinct sources:

* Filesystem
* Generated files
* Knowledge files

{% hint style="info" %}
If the size of the file contents exceeds the token limit set for the context window limit, the file will not be sent to the model.
{% endhint %}

{% hint style="info" %}
It is recommended to specify the desired source when asking the model to read a file. This ensures accurate retrieval of the intended content.
{% endhint %}
