What is a KRA~ file? A KRA~ file is a backup of a Krita image document ( .KRA file). It contains a previous version of the document, saved automatically by Krita. By default, Krita automatically saves one KRA~ file for each KRA file, in the same folder as the original document.

More Information Krita is a digital painting application available for Windows, macOS, and Linux. It allows illustrators to create concept art, comics, animation frames, pin-ups, and other illustrations. These layer-based images are saved as KRA files. To allow illustrators to quickly revert to the previous version of an illustration, Krita stores each illustration's last-saved version in a KRA~ file. Thus, when an illustrator saves a KRA file for the second time, Krita automatically creates an accompanying KRA~ file. This file uses the same base filename as its associated KRA file. Krita continually updates (overwrites) the KRA~ file as an illustrator saves new versions of their illustration. How to configure KRA~ file creation Optionally, Krita users can configure whether and how the app creates KRA~ files. To do so: Open the app's Settings or Preferences menu. On the General screen, select the File Handling tab. If you want to stop Krita from creating KRA~ files, de-select the Create a Backup File on Saving checkbox. Otherwise, modify Krita's KRA~ file creation settings as you desire.
