What is the difference between .cff and .pfm?

Description: The Common File Format (CFF) is a standardized file structure designed to facilitate the sharing, exchange, and preservation of data across various platforms and applications. It is not tied to a specific domain but is rather a generic format that can be adopted by different types of software and systems for a wide range of data types. The CFF aims to provide a common framework that ensures data interoperability and accessibility, making it easier for users to work with data across different tools without the need for extensive conversions.; A Printer Font Metrics (PFM) file is a type of file associated with Adobe Type 1 fonts used in Microsoft Windows. It contains metric information about a font, such as character widths, heights, and kerning pairs, which are essential for correctly displaying and printing text. The PFM file works in conjunction with a PFB (Printer Font Binary) file, which contains the actual font outline data.
