What is a KNO file?

A KNO file is a data file created by DigIN, a program used for information management and knowledge discovery. It contains a "break model," which classifies the information from a set of digital resources (documents, webpages, etc.) into a structure that allows patterns, relationships, and origins of data to be discovered. KNO files organize data by content, context, and structure, using a figure referred to as a Borromean ring.

More Information

Break models organize data in such a way that information can be derived and extracted at any level of granularity that the user selects. Each break model can be analyzed at multiple levels of granularity and may be used to generate additional break models.

SuperMemo is a knowledge memorization app published by SuperMemo World. In the past, the app was available primarily for Windows and supported generalized memorization, via question-and-answer flashcards. (Current versions of SuperMemo are available for Windows and mobile devices, and they specialize in language-learning courses that consist of vocabulary words and phrases.)

These versions of SuperMemo save users' flashcard collections as KNO files. To create a new KNO file, users select File → New collection. SuperMemo then creates the KNO file in its SuperMemo/​systems directory. In some versions of SuperMemo, users can also manually back up their KNO files to additional locations.

How to open a KNO file

You can open a KNO file in SuperMemo 18 (Windows) and some preceding versions of SuperMemo. Note that KNO files created by newer versions of SuperMemo may not open in older versions of the program (for example, a KNO file created by SuperMemo 18 may not open in SuperMemo 15).
