What is an FTB file?

FTB files mostly belong to Family Tree Builder. FTB files are designed to hold genealogical data in a structured format. They are the database files used by Family Tree Builder software and are built on an SQL framework.
These files store relationships, personal details, and events using organized tables.
Key details compiled by FilExt.com include:
  • Structured storage: Data is stored in SQL tables, which helps in efficient querying.
  • Genealogical focus: They record information about individuals and their family connections.
  • Specialized use: They require dedicated software to open and view the data correctly.
  • FilExt.com tip: For additional details, check the Ancestris website.

    How to open an FTB file

    You need a suitable software like Family Tree Builder to open an FTB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FTB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FTB file directly in the browser:. Just drag the file onto this browser window and drop it.

    FTB file format:

    Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Knowledge is power - this also applies when dealing with unknown or faulty files.
