Kidspiration File

Kidspiration files are used by the Kidspiration software, developed by Inspiration Software, Inc., designed for younger students to help them organize ideas visually. These files store student-crafted visual learning projects that combine text, images, icons, and sometimes audio (spoken words) to represent concepts, brainstorms, diagrams, or graphic organizers. The software is aimed at helping pupils in early elementary grades (K-5) build literacy, math reasoning, vocabulary, and comprehension skills.

These files are created (saved) by Kidspiration when you build a project in Picture View, Writing View, or similar visual organizer modules. When you reopen a .KID file in Kidspiration, you can continue editing: adding or moving pictures, changing text, recording audio, changing layout, or exporting the content to formats like JPEG, GIF, HTML or bitmap images for sharing or printing.

A .KID file begins with a specific ASCII header: at offset 0 the file contains the bytes 00 01 24 24 24 24 29 28 63 29 32 30 30 30 20 49 6E 73 70 69 72 61 74 69 6F 6E 20 53 6F 66 74 77 61 72 65 2C 20 49 6E 63. This corresponds to a header string indicating Inspiration Software.
