# File Attachments

> Attach files to tasks for Claude to reference

File attachments let you upload files directly to a task. These files are included in Claude's prompt as additional context.

## How It Works

<Steps>
  <Step title="Open a task">
    Click on any task card to open the detail view.
  </Step>

  <Step title="Upload files">
    Use the attachment section to upload one or more files. Files are stored in Claude Board's data directory.
  </Step>

  <Step title="Claude receives them">
    When the agent starts, attached files are included in the prompt. Claude can read their contents as part of the task context.
  </Step>
</Steps>

## Supported Files

Attachments work best with text-based files that Claude can read directly:

* Source code files (`.js`, `.py`, `.ts`, etc.)
* Data files (`.json`, `.csv`, `.yaml`)
* Documents (`.txt`, `.md`)
* Images (`.png`, `.jpg`) — included as visual context

<Note>Large binary files are stored but may not be useful as prompt context. Keep attachments focused and relevant to the task.</Note>

## Managing Attachments

* Attach files when creating a task or from the task detail view
* Remove attachments by clicking the delete icon next to each file
* Attachments are deleted when the task is deleted
