The FI extension stands for Flex Interface files. This type of software development is utilizing FI files for the construction of user interfaces and they can contain structure for layout, components, and interactive elements of the project.

In some cases, any text editing tool like Notepad or Notepad++ can be used to open and make minor alterations in the FI files. This kind of method could be risky due to the complex syntax used in these files so it should be performed with utmost care.
