# 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.
