What it is

wxHexEditor is a free hex and disk editor for examining and changing binary data, with a particular focus on large files on Linux. It uses 64-bit file descriptors and supports files or devices up to 2^64 bytes. The site reports about 25 MB of memory use with multiple files larger than 8 GB open, without copying the whole file into RAM. You can insert or delete bytes without creating a temporary file, compare binary files and merge nearby results, and use its integrated x86 disassembly. It can open devices on Linux, Windows, and Mac OS X for disk and sector editing; 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 saving selections as dump files. Downloads are listed for Linux, Mac Intel, and Win32. The latest release event listed on the home page is version 0.24 Beta, dated December 31, 2017. The site’s supported languages are English, Turkish, and partially Russian.
