# File Store

## **Indexing** Files

Follow these steps to upload a file and create a new Knowledge Source:

{% hint style="info" %}
ddd
{% endhint %}

1. In the ClearFeed WebApp, go to **AI →** [**Knowledge Sources**](https://web.clearfeed.app/knowledge-sources) from the left navigation bar.
2. Hover over the **Add Knowledge Source** dropdown in the top-right corner and select **File Store**.
3. A side drawer will open. Fill in the following:
   * **Name** → Display title for this Knowledge Source in ClearFeed.
   * **Tags** → Add identifiers to organize the Knowledge Source. *(If no tags are added, a default tag may be assigned. You can always edit tags later.)*
   * **File Type** → Supported formats include:

     * PDF
     * DOCX
     * TXT
     * HTML
     * Markdown (max 100MB per file)

     <div data-gb-custom-block data-tag="hint" data-style="warning" class="hint hint-warning"><p>Each Knowledge Source supports a single file. To add multiple files, create separate Knowledge Sources or use Google Drive.</p></div>
4. Click **Save**. The file will begin indexing:

   * **Initiated** → Queued and will start indexing soon.
   * **In Progress** → Currently being indexed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.clearfeed.ai/clearfeed-help-center/clearfeed-ai/knowledge-sources/indexing-knowledge-sources/file-store.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
