How to open ARFF files

Did your computer fail to open an ARFF file? We explain what ARFF files are and recommend software that we know can open or convert your files.

What is an ARFF file?

ARFF files are Attribute-Relation File Format files, which you can read more about below.

The ARFF file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So an ARFF opener may not be able to open all kinds of ARFF files. In this case, though, we only know of one specific use.
