What wxHexEditor is

wxHexEditor is a free hex and disk editor for examining and changing binary data, with particular emphasis on large files on Linux. It uses 64-bit file descriptors and can handle files or devices up to 2^64 bytes. The program does not load an entire file into RAM, and the site reports about 25 MB of memory use with multiple files larger than 8 GB open. It can insert or remove bytes without making a temporary file, compare binary files and merge nearby results, and perform x86 disassembly. Disk access includes devices and sectors on Linux, Windows, and Mac OS X; raw-sector editing can be used to work on partition tables and filesystems or recover data. Other tools include many encodings, checksum functions, XOR operations, color tags, and selection dumps. Downloads are listed for Linux, Mac Intel, and Win32. The latest listed release is version 0.24 Beta, dated December 31, 2017.
