# Work with Files

> Use agent.download_files to navigate websites, find download links, and retrieve files. Access downloaded files via presigned URLs.

In a browser automation, `agent.download_files` navigates a page, finds the download link, and captures the file. Downloaded files are stored in Skyvern's cloud storage and returned as presigned URLs in the response.

If you're building agents in the Cloud UI instead, use the File Download block. See [Block Types and Configuration](/cloud/building-agents/configure-blocks).

## Download a file

<CodeGroup>
  ```python Python theme={null}
  browser = await skyvern.launch_cloud_browser()
  page = await browser.get_working_page()

  await page.goto("https://portal.example.com")
  await page.agent.login(credential_type="skyvern", credential_id="cred_123")

  result = await page.agent.download_files(
      "Download the Q4 2025 financial report",
      download_suffix=".pdf",
      download_timeout=30,
  )

  for file in result.downloaded_files or []:
      print(f"File: {file.filename}")
      print(f"URL: {file.url}")
      print(f"Checksum: {file.checksum}")

  await browser.close()
  ```

  ```typescript TypeScript theme={null}
  const browser = await skyvern.launchCloudBrowser();
  const page = await browser.getWorkingPage();

  await page.goto("https://portal.example.com");
  await page.agent.login("skyvern", { credentialId: "cred_123" });

  const result = await page.agent.downloadFiles(
    "Download the Q4 2025 financial report",
    { downloadSuffix: ".pdf", downloadTimeout: 30 },
  );

  for (const file of result.downloadedFiles ?? []) {
    console.log(`File: ${file.filename}`);
    console.log(`URL: ${file.url}`);
    console.log(`Checksum: ${file.checksum}`);
  }

  await browser.close();
  ```

## Parameters

| Parameter           | Type               | Required | Description                                                                                                                                                                                                                          |
| ------------------- | ------------------ | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `prompt`            | `str` / `string`   | Yes      | Describe what to download. The agent navigates the page to find and click the download link.                                                                                                                                         |
| `url`               | `str` / `string`   | No       | URL to navigate to before downloading. Defaults to the current page URL.                                                                                                                                                             |
| `download_suffix`   | `str` / `string`   | No       | Filename hint prepended to the saved file (e.g., `"invoice"` → `invoice.pdf`). **Not a validator**; mismatched extensions don't fail the run. Omit this to get a system-generated filename like `download-<timestamp>-<random>.pdf`. |
| `download_timeout`  | `float` / `number` | No       | Soft hint (seconds) for how long to wait for a download to start. Not a hard cap; the overall `timeout` below governs failure.                                                                                                       |
| `max_steps_per_run` | `int` / `number`   | No       | Cap AI steps for the download navigation.                                                                                                                                                                                            |
| `timeout`           | `float` / `number` | No       | Total timeout in seconds (default: 1800).                                                                                                                                                                                            |

See the [`WorkflowRunResponse`](/sdk-reference/workflows/run-workflow#returns-workflowrunresponse) reference for the full field list.

### FileInfo fields

Each file in `downloaded_files` has:

| Field         | Type               | Description                                                                            |
| ------------- | ------------------ | -------------------------------------------------------------------------------------- |
| `url`         | `str`              | Presigned URL to download the file. Valid for a limited time.                          |
| `filename`    | `str \| None`      | Saved filename. Reflects `download_suffix` if you set one, otherwise system-generated. |
| `checksum`    | `str \| None`      | SHA-256 checksum for integrity verification                                            |
| `file_size`   | `int \| None`      | Size of the file in bytes                                                              |
| `modified_at` | `datetime \| None` | Last-modified timestamp if the source provides one                                     |

## Where files are stored

Files are stored in Skyvern's managed cloud storage (S3). You access them through the presigned URLs returned in `downloaded_files`. Files are not saved to your local machine automatically.

To save a file locally:

<CodeGroup>
  ```python Python theme={null}
  import requests

  for file in result.downloaded_files or []:
      response = requests.get(file.url)
      with open(file.filename or "download.pdf", "wb") as f:
          f.write(response.content)
      print(f"Saved {file.filename}")
  ```

  ```typescript TypeScript theme={null}
  import fs from "fs";

  for (const file of result.downloadedFiles ?? []) {
    const response = await fetch(file.url);
    const buffer = await response.arrayBuffer();
    fs.writeFileSync(file.filename ?? "download.pdf", Buffer.from(buffer));
    console.log(`Saved ${file.filename}`);
  }
  ```
</CodeGroup>

***

## Tips

**Set `download_suffix`** to get a predictable filename (e.g., `"invoice-q4"` → `invoice-q4.pdf`). Without it, files are saved with a system-generated name like `download-<timestamp>-<random>.pdf`. It does **not** validate or filter by extension.

**Raise the overall `timeout`** for large files. `download_timeout` is a soft hint; `timeout` is what actually fails the run.

**Verify with checksums.** The `checksum` field contains a SHA-256 hash. Compare it against expected values to verify file integrity.

**Login first.** Most download portals require authentication. Call `agent.login` before `agent.download_files` - the agent reuses the authenticated session.

## File operations in agents

If you build agents in the Cloud UI, file operations use dedicated blocks instead of `agent.download_files`:

| Block              | Purpose                                     |
| ------------------ | ------------------------------------------- |
| **File Download**  | Download files during agent execution       |
| **File Parser**    | Parse PDFs, CSVs, and Excel files           |
| **Download to S3** | Save files from URLs to Skyvern's S3        |
| **Upload to S3**   | Upload agent files to S3                    |
| **File Upload**    | Upload to your own S3 or Azure Blob Storage |

Files downloaded during an agent run accumulate in a temporary directory and can be passed between blocks using agent parameters. See [Agent Blocks Reference](/cloud/building-agents/configure-blocks) for block configuration details.
