HxD is a carefully designed and fast hex editor which, additionally to raw disk editing and modifying of main memory (RAM), handles files of any size.

The easy to use interface offers features such as searching and replacing, exporting, checksums/digests, insertion of byte patterns, a file shredder, concatenation or splitting of files, statistics and much more.

Editing works like in a text editor with a focus on a simple and task-oriented operation, as such functions were streamlined to hide differences that are purely technical.
For example, drives and memory are presented similar to a file and are shown as a whole, in contrast to a sector/region-limited view that cuts off data which potentially belongs together. Drives and memory can be edited the same way as a regular file including support for undo. In addition memory-sections define a foldable region and inaccessible sections are hidden by default.

Furthermore a lot of effort was put into making operations fast and efficient, instead of forcing you to use specialized functions for technical reasons or arbitrarily limiting file sizes. This includes a responsive interface and progress indicators for lengthy operations.

Notes
Disk-Editor
To use the disk editor under Windows NT/2000/XP/2003/Vista/7 and higher you have to be an administrator or have the appropriate privileges.
Starting with Vista you need to manually unmount the hard disk to successfully write to it, or in other words: make sure the disk you edit has no mounted file system. More details in this forum thread. A system drive (the one where Windows is installed on) cannot be written to while Windows is running. In order to still accomplish that, you will have to execute HxD from a boot CD/DVD like PartBE or VistaPE and edit the system disk from there.
Windows NT 4
If the RAM-editor doesn't show any processes under Windows NT 4 you most likely don't have PSAPI.DLL installed on your system. You can get it from Microsoft (PSAPI.DLL Download) and copy the DLL into the %windir%System directory.
HxD was only tested for Windows NT 4 SP 6, though it should work with versions prior to service pack 6.
Windown NT 4 SP1 and newer are also supported, if WININET.DLL is added, through IE 3.02 or newer.
