What is an FBF file?
An .FBF file is typically a backup file or a specialized data file used by several different software programs. The most common use is as a backup archive created by Norton Ghost or Symantec Backup Exec. However, the .FBF extension is also used for serialized game save files in the Unity game engine, compressed genealogy backups in My Family Tree, navigation data in the Fugro Starfix positioning system, and as a Free Backup Fix Backup File created by Promosoft.
How to identify and view FBF files
Because the .FBF extension has multiple possible meanings, it can be hard to know which software to use. You can use viewer.online/fbf to analyze .FBF files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
How to open FBF files locally
To open an .FBF file on your computer, you usually must use the original software that created it. For Symantec backups, you need Symantec Backup Exec to restore the data. For a Free Backup Fix Backup File, you need the Promosoft backup utility. For Unity game saves, the file is read automatically by the specific game when you load your progress.
If your .FBF file is a backup from the My Family Tree software, it is actually a standard .ZIP archive. You can rename the file extension from .FBF to .ZIP and extract the contents using an archive tool like 7-Zip or WinRAR.
Summary
viewer.online/fbf is useful for identifying, inspecting, and understanding .FBF files without installing software or dealing with compatibility problems. If you do not know the origin of your .FBF file, uploading it for analysis is the safest first step.
