The HPR file extension is used by ATLAS.ti, a powerful workbench for the qualitative analysis of large bodies of textual, graphical, audio and video data. It offers a variety of tools for accomplishing the tasks associated with any systematic approach to "soft" data--i.e., material which cannot be analyzed by formal, statistical approaches in meaningful ways.

In the course of such a qualitative analysis, ATLAS.ti helps you to uncover the complex phenomena hidden in your data in an exploratory way.

For coping with the inherent complexity of the tasks and the data, ATLAS.ti offers a work environment that is designed to keep you focused on the material itself.

ATLAS.ti stands for "Archiv fuer Technik, Lebenswelt und Alltagssprache". Translated: archive for "technology, the life world and everyday language". The extension "ti" (pronounced TEE EYE) stands for text interpretation.
