    output='archive.zip',
    password='secret123'

API Reference

send_files_or_folders(paths, max_downloads=1, tunnel_ngrok=False, output=None, password=None, delete_after=True)

Send one or more files/folders as a one-time or limited-use download link, with optional ngrok public URL and custom zip naming.

Parameters:

• paths (List[str]): List of file or folder paths to send.
• max_downloads (int, default 1): Maximum number of downloads allowed before the link expires.
• tunnel_ngrok (bool, default False): If True, launches ngrok and returns a public URL.
• output (str, optional): Output zip file name. If not provided, a smart name is chosen.
• password (str, optional): Password required to download the file (HTTP Basic Auth).
• delete_after (bool, default True): Delete the zip after transfer (unless a custom output name is used).

Returns:

• local_url (str): The local download URL.
• public_url (str or None): The ngrok public download URL, or None if not using ngrok.
• token (str): The secure token for the download.

Example return:

(
  'http://localhost:9000/download?token=abc123',
  'https://xxxx.ngrok-free.app/download?token=abc123',
  'abc123'
)

Raises:

• FileNotFoundError if any path does not exist.
• RuntimeError if ngrok is not installed or fails to start.

Windows Firewall: Open Port 9000

To allow downloads from other devices, you must open port 9000 in Windows Firewall:

1. Open Windows Defender Firewall with Advanced Security.
2. Click Inbound Rules > New Rule...
3. Select Port > Next
4. Select TCP and enter 9000 > Next
5. Allow the connection > Next
6. Check all profiles (Domain, Private, Public) > Next
7. Name the rule (e.g., pyonesend 9000) > Finish

Or, run this in an Administrator Command Prompt:

netsh advfirewall firewall add rule name="pyonesend 9000" dir=in action=allow protocol=TCP localport=9000

---

ngrok Setup

1. Download ngrok:
   https://ngrok.com/download
2. Install ngrok:
   Unzip and place ngrok.exe in a folder in your PATH (e.g., C:\Windows or your project folder).
3. (Optional) Authenticate ngrok:
   Sign up at ngrok.com, get your auth token, and run:

   ngrok config add-authtoken <YOUR_AUTH_TOKEN>

4. No need to run ngrok manually – pyonesend will launch it for you!

---

Security Notes

• By default, runs over HTTP (insecure). For production, use real SSL certs.
• ngrok links are public; anyone with the link can download until the limit is reached.
• No files are kept after transfer unless you specify an output zip name.

FAQ / Troubleshooting

Q: Why do I get ERR_NGROK_8012 or 3200?
A: Make sure the server is running and ngrok is tunneling the correct port (default: 9000). Only one ngrok process per port.

Q: Why do I get 'Invalid token'?
A: Use the download link and token from the current server run. Restart the server for a new link.

Q: How do I keep the server running for manual testing?
A: Use the import example with input("Press Enter to exit...") to keep the tunnel alive.
