File Formats

FydeOS installation media are published as raw disk images. Earlier releases used the .img extension with xz as the compressing tool; the current build process outputs .bin with simpler zip. Most flashing utility accepts the zip file directly. If you insist on unarchiving and exposing the image file, the extension is cosmetic — rename .bin to .img if a flashing utility prefers that suffix. Why not .iso?
