What is an I3F file?

I3F files mostly belong to Microsoft Fax and Scan.

The I3F files are fax document files that use the Microsoft Compound file structure. They are designed to store fax images and related data. In some cases the format is also known as an Image Capture Format, a term tied to the Image3F implementation.
Key points about I3F files include:

Format: Uses a structured, compound file system to hold image streams and metadata.
Usage: Stores fax images and their associated information.
Alternative name: Sometimes referred to as an Image Capture Format file.

To open an I3F file, consider using fax viewer software such as Microsoft Fax and Scan or other document conversion tools that support compound file formats. Converting the file to a more common image format like TIFF or PDF may simplify viewing and editing.

Microsoft Compound File is a complex container format used by some versions of Microsoft Office and other Windows-centric applications. It has features similar to those of a filesystem format. The Compound Document format is always starting with the bytes D0 CF 11 E0 A1 B1 1A E1. Sections and streams in the file are named Page Images, Page Stream List, Fax.ID and Valid. Most of these files are 20 KB to 230 KB in size. The file type was developed 10 years ago and is still in use today. The file name Fax_20180601Z.I3F is characteristic of these files.
