Convert UDB to another file type
To convert UDB Databases to another format, you need Autodesk Moldflow or other Database software.
Convert a file to UDB
To convert other file formats to the "Proprietary Database File" file type, you need software like Autodesk Moldflow or a similar tool.
About UDB files
The .UDB file extension most commonly represents a Moldflow Material Database utilized by Autodesk Moldflow. These files store highly specialized data regarding the rheological, thermal, and mechanical properties of plastic resins used in injection molding simulations. Outside of the Autodesk ecosystem, the .UDB extension is heavily fragmented. It frequently acts as a generic database container, such as an UltraLite persistent storage database by SAP, a standard SQLite version 3 database, or an Absolute Database file for Delphi developers using ComponentAce Absolute Database.
Users often need to convert .UDB files because the data is trapped inside proprietary or specialized database engines. An Autodesk material file cannot be queried with standard SQL tools, requiring costly subscriptions simply to view material specifications. Furthermore, fragmented database types mean that a .UDB file from SAP UltraLite will fail to open in standard SQLite browsers. If you need to analyze the data, your best conversion targets are standard CSV, SQL, or JSON files. Converting to these text-based formats extracts the raw tables but will discard proprietary application logic, custom indices, and encrypted views.
This file format is exceptionally difficult to open or convert universally because the extension provides no guarantee of the internal file structure. If the file is a proprietary binary Moldflow database, often only the original software can properly read or export the data. Standard online converters fail because they blindly assume all .UDB files are SQLite containers. We can identify the true format, inspect the internal structure, and show readable text. If our analysis detects a supported underlying format like SQLite, viewing or conversion may still be possible.
Convert.Guru analyzes your UDB file, detects the exact format, and lets you read the text inside.
If you want to convert UDB file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use Autodesk Moldflow or similar software from the "Material Database Storage" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to UDB, try Autodesk Moldflow or another comparable tool in the "Material Database Storage" category.
The UDB 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 UDB converter.
