What is a .FTR file?
A .FTR file is a type of system file specifically used by the IRIX operating system, which was developed by Silicon Graphics. This file extension stands for "File Type Rules." The IRIX operating system was primarily used on Silicon Graphics' workstations and servers from 1988 until it was discontinued in 2006.
The purpose of an FTR file is to store rules that define how the IRIX system displays and manages different types of files. These rules are crucial for the operating system to identify and interact with various file types in a consistent manner. Each FTR file includes several important components: 1. **Type Declaration (TYPE)**: This part names the file type, helping the system to categorize files according to the rules specified. 2. **Match Declaration (MATCH)**: This section describes the criteria for identifying files of the type named. It tells the system how to recognize these files based on their characteristics. 3. **Command Open Declaration (CMD OPEN)**: This defines what actions are available to the user when they interact with the file, such as what should happen when a user double-clicks on a file. 4. **Legend (LEGEND)**: This optional setting provides a description of the file type, which can be used for user reference. 5. **Icon (ICON)**: This specifies what icons represent the file type in the user interface, enhancing visual identification.
To view or edit FTR files, you can use any basic text editor because these files are essentially text-based. Some of the common programs that can open FTR files include: - **Microsoft Notepad**: A simple text editor included with Microsoft Windows operating systems. - **Apple TextEdit**: A text editor included with macOS. - **Vim**: A highly configurable text editor often used by programmers. - **GNU Emacs**: Another extensible and customizable text editor popular among developers. - **Google Chrome Text**: Available on Chrome OS for basic text editing.
Although GitHub Atom was also a popular choice, it has been discontinued. However, other advanced text editors like Microsoft Visual Studio Code can also handle FTR files effectively.
Understanding and editing FTR files might be necessary for those maintaining or using legacy Silicon Graphics systems, as these files play a critical role in how the IRIX operating system manages file interactions.
