Edit binary files and raw disk sectors with HXD Hex Editor

Every now and again, I bump into the need to edit a compiled file.  This is often some kind of executable or other resource file that I don’t have the source or an appropriate compiler for. Finding an appropriate editor that’s easy to use and reasonably priced isn’t as easy as you might think.  That’s why I like HXD Hex Editor. It’s a binary editing tool for Windows.

HXD is a fast hex editor that handles binary files of any size.  Additionally, the application also allows you to perform raw disk editing as well as modifying the contents of your computer’s RAM.   It’s easy to use interface features search and replace, exporting, checksums/digests, and insertion of byte patterns.  It also offers a file shredder, concatenation or splitting of files, statistics and more.

Editing a binary file with HXD Hex Editor works like in any text editor.  Its functions are streamlined to hide differences that are purely technical.  Drives and memory are presented as a file and are shown as a whole, unlike other editors which may limit data on the screen 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 file, and includes support for undo. Memory-sections that define a foldable region and inaccessible sections are hidden by default.

How to recover lost data from a crashed application

What if the application in which you were working has crashed, and your precious document has been lost? This could be a question without an answer, if you cannot read the information saved by the Windows OS in your PC’s RAM.

Also known as memory address space, this is where all the applications that run on your computer load there content for further use by the operating system. In case you cannot read its content, you won’t be able to recover your lost data. But with DumpIt, this is actually possible. All you have to do is to double-click this executable and this tiny utility will generate a copy of your PC’s physical memory in the current directory.

This copy is nothing else but a huge binary file which has to be read with a hex editor in order to be able to identify the content of your lost document. Free Hex Editor Neo can be a good choice to cover all this file. All you have to do is launch the program, access the Search function and type a word or phrase from the lost document. For Microsoft Word users, check the Unicode string option and search again. In this way the program will locate immediately the Word file.

DumpIt is free to use and it has been developed as a fusion of win32dd and win64dd (former products with the same functionality developed by the MoonSols company) in one executable. It has only 203 KB of memory, a portable character, and its easy to use. There are rarely occasions when you will actually use this program, but its unique utility makes it a must-have tool when such a disaster strikes.
