About BDP files
The .BDP file is primarily a Badmail queue file or Backup Data File generated by Microsoft Exchange Server and the Microsoft IIS SMTP Service. These files are created automatically when an email message cannot be delivered to its intended recipient and also cannot be returned to the original sender. The system essentially gives up on routing the message and dumps the data into a designated Badmail folder. The primary disadvantage of the .BDP format is that it is a proprietary, server-side log rather than a standard email format. These files are difficult to open, cannot be imported directly into standard email clients like Microsoft Outlook, and frequently cause massive storage issues by quietly filling up server hard drives during spam attacks. Users typically need to convert .BDP files to TXT, EML, or PDF to comfortably read the bounce headers, understand why the email failed, and extract any readable message content. Because this is a closed, proprietary format designed for system diagnostics, standard online converters often fail to process it. Often, only the original Microsoft environment can properly read or export the diagnostic data. However, just drag and drop your file onto convert.guru to identify the format, view its raw contents, and extract text. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your BDP file, detects the exact format, and lets you read the text inside.
If you want to convert BDP file to TXT, RTF, DOC, DOCX, ODT, PAGES, TEX, LATEX, MD, MARKDOWN, LOG or NFO, you can use Microsoft Exchange or similar software from the "Server Diagnostic Mail Storage" category. In the File menu, look for Save As… or Export….
To convert PDF, DOC, ASC, TODO, NFO, MEMO, README, DOCX, JPG, TXT, NOTE or RTF files to BDP, try Microsoft Exchange or another comparable tool in the "Server Diagnostic Mail Storage" category.
The BDP Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BDP converter.
