What is a .EFL file?

The .EFL file extension stands for External Format Language File. It's a special kind of file that is used by a program called NFBTRANS. This program is made by the National Federation of the Blind (NFB) and its main job is to translate regular text into Grade Two braille, which is a form of braille used by visually impaired people to read and write.

An .EFL file contains specific instructions or rules. These rules tell the NFBTRANS program exactly how to change or translate a normal text file into braille. Think of it like giving the program a recipe to follow so that it knows what to do with the text file to make it readable in braille.

You can only open and use .EFL files with the NFBTRANS program, which is provided by the NFB. This is because the .EFL files are designed to work specifically with this program.

There are two types of .EFL files. Some are called global .EFL files, which means they can be used with many different text files. They give general instructions that can apply to translating any text file into braille. The other type is specific .EFL files. These are made to work with just one particular text file. To keep things organized, a specific .EFL file will have the same name as the text file it's meant to work with. For example, if you have a text file named "story.txt," the .EFL file with the instructions for translating that specific text would be named "story.efl." In summary, .EFL files are important for converting text to braille using the NFBTRANS program, and they come in two varieties to provide flexibility in how text files are processed.
