Disk editing allows PC users to have more influence on the performance of their computers. Of course, it requires a ton of qualifications from a developers standpoint. In order to make disc editing easier and faster, advanced PC users download hex editors. HxD Editor is a free hex editor for Windows PCs. Its main features are disk editing and modifying the main memory. Apart from the above, the programme can manage files of any size stored on a device. 

The interface is fairly easy-to-use though it might be too challenging for a novice PC user. The range of features includes file searching, replacing, exporting, byte pattern insertion, splitting or concatenation, file shredding, creating digest or checksums, and many more. 

How can HxD Editor Boost Your PC?

HxD Editor is a simple tool based on a task-oriented operation. It mainly works as a text editor in order to not overload a user with technical details. You can stay updated on the state of memory as well. You can edit drives and memory files similarly to any files.

In case there’s a disk or file fragment that can be accessed and edited, HxD Editor hides it by default. This way, a user can avoid confusion and save a ton of their time. For lengthy operations, there’s a flexible progress bar and frequent status update. Moreover, developers placed a huge emphasis on improving the speed and the efficiency of operations - HxD Editor doesn’t put too big of a strain on system performances and can essentially run in a background mode.

HxD Editor is completely free of charge for both personal use and work teams. Distributing the tool is highly encouraged - you wouldn’t be risking paying any fines. Keep in mind, however, that selling HxD Editor is not allowed. The tool is available for Windows 95, 98, ME, NT, 4, 2000, XP, 2003, Vista, or 7.

HxD Editor is an advanced disk editor and file manager for experienced PC users. It provides PC users with access to advanced features - such as editing the disk source code, byte patterns insertion, and many more. HxD Editor is completely free to use - there are no access limitations. The interface is simple and block-based - however, the panels are not easily readable for beginners.

What's new in version?

New: open source plugin interface to extend the data inspector:

  • https://github.com/maelh/hxd-plugin-framework
  • supports dll plugins made in C, C++, Delphi or any other language which can deal with a C-like interface
  • includes example plugins

New: array navigation toolbar in datainspector (next/previous/first/last element):

  • allows to navigate types like ad-hoc arrays, that span the entire stream / file, extending left and right from the current element shown in the datainspector
  • all fixed-width data types support navigating forwards and backwards by default
  • backward navigation needs special support for variable-width data types like UTF-8
  • since UTF-8 is self-synchronizing, determining the previous element is possible (however, x86 assembly, for example, cannot be supported, since trailing bytes in an instruction encoding can also appear as leading bytes, which therefore only allows for an unambigious forward scan)
  • New: unintrusive pointer type support in data inspector
  • clickable goto link, which is right aligned next to integer type name
  • implicitly treats integer types as pointers / addresses / offsets
  • signed integers are treated as relative offsets, unsigned integers as absolute offsets
  • avoids cluttering the UI with many more rows by having each integer row have a dual function (acting as pointer as well as plain integer)
  • typed pointers and pointers that use complex adressing schemes (such as using a lookup table, or computing of an address based on parameters instead of a simple immediate value), will follow with structure views
  • New: added Int24 and UInt24 types to data inspector (useful for wav files)
  • be sure to reset the data inspector row order in the options, if new types appear in the last rows
  • New: separate portable and installable versions (also reduces number of wizard pages)
  • portable setup runs with least privileges
  • portable setup defaults to desktop folder
  • Enhancement: reduce flickering in data inspector when resizing or during fast selection, especially for the text box
  • Enhancement: unfold a section if a goto command jumps into it
  • Enhancement: implemented new TXmTabControl to enable Ctrl+(Shift+)Tab navigation in Search and Replace windows
  • behaves like native TPageControls from Delphi (native TTabControls do not support keyboard shortcuts for tab switching)
  • allows focusing the tabs itself to allow navigating with Left/Right arrow keys, yet still focuses the first child control when switching tabs, as required
  • Enhancement: edit controls in block selection windows only validate the entry on losing focus
  • allows for more flexible editing and temporarily invalid states
  • Change: for more consistency in error messages, the goto dialog always displays the computed target offset, instead of the text in the offset text box (which can contain absolute or relative offsets)
  • Change: rename optical disk to optical disc (used disk for consistency in the past, but disc is just more common)
  • Change: turn all http links into https ones
  • Fix: data inspector ignores leading and trailing whitespace where not relevant to the data type (e.g., removing for integers, but keeping for character types)
  • Fix: always treat integers as unsigned when displaying them in hexadecimal
  • Fix: physical floppy disk drives would show a too small size (limited like the logical ones)
  • Fix: writing to floppy disks could fail, because they did not get locked and unmounted
  • Fix: make the height of the bottom dock normal size again (it would appear too small, making people believe no results are produced, for example when generating checksums)
  • Fix: data inspector: when data name column was too small, the splitter could be overdrawn / interrupted with white space
  • Fix: properly handle https URLs by passing INTERNET_FLAG_SECURE and do not fail on redirects from http to https
  • Fix: Setup would choose English by default, instead of picking the language based on the OS's locale
  • Fix: tab order in various windows (search and replace, and the option frames for each); correct tab order even if option frames are not shown for a certain data type
  • Fix: ensure tab switching with Ctrl+(Shift+)Tab keeps working after a switch, by setting the focus to the first control inside the tab each time a tab switch occurs
  • Fix: selections would unfold sections even if unnecessary
  • Other smaller fixes, many internal enhancements and refactorings
  • Lots of work on UTF-8 and handling grapheme cluster boundaries for future UTF-8 support in the hex editing window itself, see https://blog.mh-nexus.de/2019/06/compressing-arrays-of-integers-while-keeping-fast-indexing/
