HANMOA GUIDE

Recover an attachment from winmail.dat

If a message contains winmail.dat instead of the document you expected, ordinary attachments may be inside Outlook’s TNEF format. Inspect the names and sizes, then save the attachments you need.

  • Extract ordinary TNEF attachments
  • Up to 50MiB · 200 attachments
  • Individual files or ZIP download

From the first step to a saved result

  1. Save the email attachment

    Save winmail.dat to your device and check who sent it. Try the built-in sample first if you are unfamiliar with the format.

  2. Inspect the file list

    Choose or drop the file. Review the extracted names and sizes. For broken legacy Korean filenames, try the Korean (CP949) encoding option.

  3. Download the attachments

    Save individual files or a ZIP bundle. The tool does not execute or preview attachments; check their source and type before opening them yourself.

Try extraction without a real email

Know before you use it

  • Rich-text bodies, calendar/contact conversion, embedded Outlook messages and OLE objects are not supported.
  • Encrypted or damaged inputs may not be extractable. A TNEF file may also contain no ordinary attachments.
  • Successful extraction does not prove a file is safe. Do not open executables from unknown sources.

Frequently asked questions

Why are no attachments listed?

The input may have no ordinary attachments, or contain only unsupported objects. Ask the sender to resend the document as a normal attachment.

Do I need to sign in to my email account?

No. The tool reads a file already saved on your device. It does not need an email connection or password.

Are attachments opened automatically?

No. The tool lists names and sizes and offers downloads. Check the sender and file type before opening a download.
