What is an FDB file?
An .FDB file is a database or data storage file. It does not have a single standard format. The most common use is a relational database created by Firebird. However, an .FDB file can also be a structural foundation slab model for CSI SAFE, a Portfolio Catalog created by Extensis, or a genealogy database for Legacy Family Tree. Because an .FDB file can contain different types of data, you must know the original software to read it correctly.
How to open FDB files?
To open an .FDB file, you usually need the specific software that created it. For example, database administrators use Firebird or database management tools like DBeaver. Structural engineers use CSI SAFE to open foundation models. If you do not know which software created your file, you can use viewer.online/fdb. It can analyze .FDB files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and troubleshooting
Do not assume every .FDB file is a database. If your file does not open in a database manager, it might be a Portfolio Catalog or a structural engineering model. Never force a software program to open an unknown file. Instead, use an inspection tool to identify the correct format first. If you need the data in a different format, you can convert the file. We recommend file conversion to sensible target formats, such as .CSV or .SQL, on convert.guru.

Summary
An .FDB file can store relational databases, engineering models, or asset catalogs. viewer.online/fdb is useful for identifying, inspecting, and understanding .FDB files without installing software or dealing with compatibility problems. It helps you find the correct software to open your file quickly and safely.
