What is a FUL file?
A .FUL file serves several different purposes depending on the software that created it. Primarily, it is an HP printer firmware update file used to upgrade device software. However, it is also widely used as a Microsoft Backup File List by Microsoft, or a full database backup for Microsoft SQL Server. In industrial settings, it might be a function unit library for B&R Automation Studio or WinCC Flexible. Mobile phone technicians also use it as a flash backup in Octoplus Box.
How to open FUL files?
Because a .FUL file has multiple possible meanings, you must know its origin to open it correctly. You can apply an HP firmware update using the manufacturer's official utility. If it is a Microsoft Backup File List or a Microsoft SQL Server backup, you restore it using SQL Server Management Studio (SSMS). Do not modify these files manually with a text editor.
