About FF3 files
The .FF3 file format is predominantly used as a piping system design file generated by FluidFlow 3, a specialized engineering software suite used for fluid dynamics calculations. In about 20% of cases, .FF3 files function as serialized Java flowchart models created by the HTWG FlowchartGenerator. The primary disadvantage of the .FF3 format is its highly proprietary and closed-source nature. Engineering project files like those from FluidFlow require expensive, niche software licenses to open, view, or edit. They cannot be natively opened by web browsers, standard operating systems, or basic image viewers. Similarly, serialized Java objects are notoriously difficult to read outside the specific Java runtime environment that created them. Users usually need to convert these files into universally accessible formats like PDF, DXF, or PNG to share flowcharts or piping schematics with clients or team members. Because this file format is difficult to open or convert, standard online converters often fail. Often, only the original software can properly read or export the complex engineering data and mathematical models. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your .FF3 file to identify the format, view it, and convert it when possible. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be successful.
Convert.Guru analyzes your FF3 file, detects the exact format, and lets you read the text inside.

The FF3 Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our FF3 converter.
