If you have problems opening an email attachment, it might be due to the wrong or missing email header information.

  1. Save the attachment in your local drive (e.g. D:\data).
  2. Rename the file extension as “*.uue". (e.g. filename.uue).
  3. Right click the file and choose "Open with WinZip".
  4. Select the file “Unknown.001” and click the “Extract” button to extract the encoded file to the local drive (e.g. D:\data).
  5. Rename the file “Unknown.001” using an appropriate file extension according to the file format (e.g. Unknown.doc for Word document) to get the decoded file.
