Binary Editor Bz is a hex editor for Windows, originally written by c.mos and continued by tamachan with the original author's permission.
It opens large files through file mapping instead of loading them into memory, renders the bytes as a bitmap for spotting patterns, and parses structures described in a definition file so records can be read as fields rather than raw offsets.
