What is a BDC file

BDC files mostly belong to Bridge Designer.

BDC files come in different forms based on their specific use. In one case, they are Bridge Design files created with West Point Bridge Designer. These files store project data and simulation details for bridge engineering. You can find more details on the Bridge Contest site.
Another use of the BDC extension is for Babylon Dictionary files. These files hold lexical data used with Babylon Builder, supporting language translation and lookup functions.
Additionally, some BDC files function as Binary Data Containers that hold game assets and configuration details for titles like Black Desert Online. More game-related information is available on the Black Desert Online website.
BDC files are application-specific and must be opened with their corresponding software. Using the wrong tool may result in data misinterpretation or corruption.

  • Tip: Always use the designated program to view and edit a BDC file.
  • Tip: Avoid manual editing with general text editors.
  • Tip: Backup the file before making any changes.

How can I open a BDC file?

You need a suitable software like Bridge Designer to open a BDC file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your BDC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BDC file directly in the browser:.
