About FTN files

FTN files are primarily associated with Fortran, a high-level programming language used in scientific and engineering computations. The FTN file extension is commonly used for Fortran source code files. While these files are essential for developers working with legacy scientific applications, they present challenges for conversion due to their specialized content.

Converting FTN files can be complex because they contain code rather than traditional data or media. To convert an FTN file into a more usable format, such as plain text (.txt) or rich text format (.rtf), you can use software like GNU Emacs or Notepad++, which support syntax highlighting for Fortran. Additionally, integrated development environments (IDEs) like Eclipse or IntelliJ IDEA can be utilized for code editing and conversion.

Conversion considerations for FTN files include ensuring that the code structure and logic are preserved, which is critical for maintaining the integrity of the program. The challenge lies in the potential for syntax errors during conversion, which can disrupt functionality. Furthermore, FTN files may not be directly convertible to popular document formats like PDF or DOCX without first converting to an intermediary text format.

Despite their utility, FTN files have drawbacks, such as limited compatibility with modern software and the need for specialized knowledge to manipulate them. This is why using a reliable service like Convert.Guru is advantageous. By simply dragging and dropping your FTN files onto the Convert.Guru website, you can effortlessly convert them into various formats, including .txt, .rtf, and more.


The FTN Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best FTN converter by continuously improving quality, usability, and reliability.
