About .af2 Files
AF2 files are binary files used by the ABC FlowCharter application.
They store diagram data for flowcharts and process maps. The MIME type, application/octet-stream, indicates the file contains non‐text binary data.
- Main use: Holding structured flowchart and diagram information.
- Format: Binary data requiring specific software for interpretation.
- Editing/viewing: Typically opened with ABC FlowCharter or compatible diagram software.
They help users map out processes clearly and efficiently.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an AF2 file used for?
AF2 files are vector graphic documents used to store flowcharts, organizational charts, and process diagrams created by ABC FlowCharter. Originally developed by Micrografx (later acquired by iGrafx), these files contain shapes, connectors, and text data representing complex workflows.
How do I open an AF2 file on Windows?
You need to install iGrafx FlowCharter or the legacy Micrografx ABC FlowCharter software to open these files. Because the format is proprietary, modern standard image viewers like Photos or Paint cannot display them.
Can I convert an AF2 file to PDF or Visio?
Yes, but you usually need the original iGrafx or ABC FlowCharter software to perform the conversion. Open the file in the application and use the File > Save As or Export menu to save the diagram as a PDF or a Microsoft Visio file (.vsd).
Why does the file look like gibberish in Notepad?
AF2 files store data in a binary format, not plain text. As indicated by the generic MIME type application/octet-stream, these files require specific software to interpret the binary code into visual shapes and lines.
Is it possible to open AF2 files on a Mac?
Direct support on macOS is very limited because ABC FlowCharter is a Windows-centric application. Mac users typically need to run Windows via Parallels or Boot Camp to install the necessary software to view these diagrams.
What is the correct MIME type for serving AF2 files?
There is no standard registered MIME type for AF2 files, so they are typically served as application/octet-stream. This generic setting, described on mime-type.com, tells the web browser to treat the file as binary data and download it rather than attempting to display it.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
