Yahoo Message Archive Decoder reads Yahoo! Messenger archive files (.dat files) and presents them in a format that you can read. Unlike the utility provided by Yahoo! Messenger, using this program you can decode them without connecting to the Internet as long as you have the .dat files. You don't need the password of the message archive owner. This software supports decoding of normal conversation messages, private messages, conferences, SMS/Mobile Messages and .hst files to HTML or plain text, complete with time stamps, smileys and font formatting (typeface, bold, italic, underline, font size and colors). It supports Unicode text (Arabic, Chinese, Japanese, and all non-Latin characters).
