What is an FBK file?
An .FBK file is a backup or data file. Because many different programs use the .FBK file extension, the file content can vary. It is most commonly a Firebird database backup, a Family Tree Maker family history backup, or a Microsoft Dynamics NAV database backup. It is also widely used as an AutoCAD Civil 3D Field Book File by Autodesk to store surveying data.
How to open FBK files?
To open an .FBK file, you usually need the software that created it. For example, you must use Firebird for database backups, Microsoft Dynamics NAV for business data backups, or AutoCAD Civil 3D for field book files. If the file is a mobile backup of SMS messages, tools like SMS Backup & Restore can read it.
Identifying and Inspecting FBK Files
Because .FBK has multiple possible meanings, we recommend using viewer.online/fbk to identify the actual format of your file. This tool can analyze .FBK files to identify the exact format and creator software. It allows you to inspect the file structure, extract readable text, and check whether an online preview is available.
File Conversion
If you need to convert an .FBK file, the options depend on its true format. Survey data can often be converted to .CSV or .TXT. Database backups must usually be restored in their original software before you can export the tables to .SQL or .CSV. We recommend using convert.guru to find compatible file conversion tools and sensible target formats.
Summary
viewer.online/fbk is useful for identifying, inspecting, and understanding .FBK files without installing software or dealing with compatibility problems. It helps you safely examine unknown files and decide on the correct next steps.
