What is a(n) FFU file?
Files in the .FFU format are used by Windows to flash updates of phones using Windows. The file stores an operating system image cryptographically signed by Microsoft and including up to several update packages. The files are usually large and do not offer the option of removing update packages from the image - users can only add new packages.
How to open FFU file?
There could be multiple reasons for which the system does not support given file. In the case of FFU extension, it is probable that none of the installed programs support given file type. Therefore, user should undertake the following steps
Step 1: Install a program that supports FFU files
If an application that supports FFU files is installed on user’s system, but is not used to open such files by default, right-click on the file icon and choose "Open with" option from the menu. Next, select the proper application and check the "Always use the selected application to open this kind of files" box. The system will store this information in its registry and use the selected program to open files with FFU extension by default.

For Mac OS users the procedure is analogous – open the file menu by right-clicking on the FFU file and choose "Information" option and select "Open with program" option. From the submenu select an application and click on "Change all" button.
