ACORN to PPM Conversion: FAQ

What are ACORN files?

The ACORN file format is associated with Acorn Sprite or RISC OS Sprite and it represents a bitmap image of up to 32 bpp. ACORN images usually store application icons and screenshots, but they can also store multiple images. As the standard file format for storing bitmap images in the RISC OS system, ACORN files are usually found on computers which run this system, such as the Acorn Archimedes. RISC OS was an operating system used in the late 1980s and 1990s, and at the moment ACORN files are considered rare and obsolete.
