BLK files: Frequently Asked Questions
What are BLK files?
The BLK file format was closely linked to the Amiga, a series of personal computers that were marketed under the Commodore brand in the 1980s and 1990s. These files were designed to store bitmap images and functioned as a part of the larger Amiga IFF (Interchange File Format) collection. Since the decline of the Amiga computer, BLK files have become obsolete and can only be viewed using a limited selection of image viewer applications.
