What HxD is

HxD is a Windows hex editor for examining and changing files, raw disks, and main memory (RAM). It supports searching and replacing text, Unicode, hexadecimal values, integers, and floats, with forward, backward, and all-direction searches. Editing tools include byte-pattern insertion, file shredding, splitting and concatenation, statistics, and unlimited undo, including for disk and memory edits. Its checksum generator includes Checksum, CRCs, Custom CRC, SHA-1, SHA-512, and MD5. HxD exports source code, formatted text, HTML, Richtext, TeX, Intel HEX, and Motorola S-record files. The disk editor can read and write hard disks, floppy disks, ZIP disks, USB flash drives, CDs, and other drives. The product lists support for files up to 8EB. It is free for private and commercial use and comes in installable and portable editions. Disk editing requires appropriate privileges; beginning with Vista, a disk must be unmounted before writing. The listed current version is 2.5.0.0 for Windows XP, 2003, Vista, 7, 8, or 10.
