About MBB files

The .mbb extension is most frequently associated with Movie Magic Budgeting, the industry-standard software developed by Entertainment Partners for estimating film and TV production costs. These files contain intricate financial data, fringes, globals, and sub-budgets.

The Problem: The format is proprietary and strictly locked to the Movie Magic ecosystem. Sharing a raw .mbb file is often futile because recipients - such as financiers or line producers - cannot open it without an expensive, licensed copy of the software. Furthermore, version incompatibility is a common headache; newer versions of the software sometimes struggle to interpret legacy .mbb data correctly without conversion.

The Solution:

For Review/Approval: The best workflow is converting the budget to PDF. This ensures the formatting remains fixed and prevents unauthorized changes to the bottom line.
For Data Crunching: Convert to Excel (.XLSX) or CSV if you need to manipulate the figures in a spreadsheet or import them into accounting software.

Secondary Use Case (MozBackup):
In some legacy contexts, an .mbb file is a backup archive created by the now-defunct MozBackup tool for Mozilla Firefox or Thunderbird. These are simply standard ZIP containers with a custom extension. If your file comes from a browser backup, you can often rename the extension from .mbb to zip to extract your profile data manually without needing the original utility.

Convert.Guru analyzes your MBB file, detects the exact format, and lets you read the text inside.

Users also converted MPP, MDB, POD, MMS and GPP files.

The MBB 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 MBB converter.
