.4db — 4D Database File
4D SAS · 1985
.4db files are proprietary database files used by the 4D database management system.
Key Features
- Stores relational data, forms, and application logic.
- Proprietary binary format for 4D database system.
- Supports cross-platform operation across Windows and macOS.
- Can be used for single-user or multi-user applications.
Best For
- Developing custom business applications with 4D.
- Storing structured data in a relational format.
- Creating cross-platform database solutions.
Less Ideal For
- General-purpose data interchange between different systems.
- Storing simple, unstructured text documents.
- Web-based data storage or cloud synchronization.
- Archiving or compressing large datasets for backup.
Common Use Cases
- Storing customer information for a business.
- Managing inventory for a retail store.
- Tracking project progress in a development environment.
- Building custom business applications.
How to Open It
- The primary method to open and work with .4db files is by using the 4D development environment or its runtime applications.
- If you have a .4db file from a 4D application, you will need the corresponding 4D application or a licensed runtime to access its contents.
- For developers, the 4D IDE allows full access to create, modify, and query the database stored within the .4db file.
- End-users typically interact with the data through the user interface provided by the 4D application, not by directly opening the .4db file itself.
What is a .4db file?
The .4db file extension is primarily associated with 4D, a powerful cross-platform database management system. These files contain the entire structure and data of a 4D database, acting as the core component for applications built with this software. They are designed to store relational data, manage user access, and facilitate complex queries. Because they are proprietary to the 4D ecosystem, they are typically only accessible and manageable through 4D's own development tools and runtime environments. Opening or manipulating these files outside of 4D requires specialized knowledge and software.

No, .4db is a proprietary format developed and owned by 4D SAS.
Technical Details
A .4db file is a binary file that encapsulates the entire data store for a 4D application. This includes tables, fields, indexes, forms, and program code. It's a self-contained database file, meaning all essential information for the application's data management resides within this single file. The internal structure is optimized for 4D's specific operations and is not designed for direct reading or editing by generic text or hex editors.
