Extract text from Database files (HXD)
To convert HXD databases to another format, you need Microsoft Exchange or other Database software.
To convert other file formats to the "Mail Transport Database" file type, you need software like Microsoft Exchange or a similar tool.
The .HXD file format primarily functions as a transport database for Microsoft Exchange Server. It temporarily stores email messages in transit before they reach the final mailbox. Another major use case is game data asset storage for Honkai Impact 3rd, developed by miHoYo. In this context, the file is often a disguised 7Z archive containing audio, models, or textures. Additionally, it is occasionally used as a compiled Help index file or a data file for the HxD Hex Editor.
Users often encounter .HXD files when managing server backups or attempting to mod game files. The format poses significant disadvantages. Exchange database files are proprietary, highly sensitive to corruption, and completely useless without a running Exchange environment. They cannot be directly opened on a standard desktop. Game asset files are equally frustrating; they lack native operating system support and sometimes employ custom structural modifications to prevent data extraction.
For game modders, the target format is usually ZIP or 7Z to extract internal textures, though renaming the extension is often the first step. For database administrators, the goal is typically converting stranded emails into PST or EML formats, which requires expensive specialized forensic software.
These files are extremely difficult to open because there is no universal specification. Only the original software can properly read or export the data. Because it is a closed, proprietary format, standard online converters fail to process it. If our analysis detects a supported underlying or embedded format - such as a standard 7-Zip container within the game asset - viewing or conversion may still be possible.
Convert.Guru analyzes your HXD file, detects the exact format, and lets you read the text inside.
Users also converted RSRC_1, RODATA and FMF files.

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 HXD converter.
