Save data in the compressed Zipped Image format.Import or export your binary data, or just drag-and-drop data to/from another applications.Edit files locked by the system or by another application.Open, save, paste, or drag-and-drop hundreds gigabytes of data within a second.View and edit the hidden data the other hex editors won't even show you.Real-time tracking of the changes made to the file by another application.Support for OLE compound files, NTFS alternate streams, sparse files, and more!.Unlimited multilevel Undo and Redo: you are never at risk of losing your data.Support for multi-byte and Unicode character sets.Edits contents of any file, memory area, logical disks and physical drives.Supports drives and files of unlimited size (up to the NTFS theoretical limit).These, and hundreds of similar tasks such as low-level disk imaging and cloning, makes this hex editor/viewer a must-have tool for anyone who needs a hex editor. Make sure you have a backup before modifying any files using a hex editor.Use FlexHex for inspecting binary output, editing the raw data contents of a file or a disk, examining the structure of proprietary closed-format data files or old data in unknown formats, quick fixing problems with executable files or flash drives, creating binary files for test runs, copying and pasting a gigabyte large chunk of data, and more. Editing a raw binary file is not recommended for the feint of heart - modify just one character in a file could potentially render it useless.

Instead of going back to recompile you code, a simple hex edit might be all you need to test out a verification pattern. Debugging & Editingįinally the last main reason you might use a hex editor is if you are a programmer who is debugging your code. This depends greatly on the type of file and what information you are looking for, but using a hex editor is useful in determining what exactly resides within a file. In addition to looking into game files, sometimes you can glean other important information from a saved file that you otherwise might not have access to. However, some games still allow you to edit certain variables, such as in Sonic Spinball. Many modern games include either compression or encryption which make it many times more difficult to decompile the save state or game.

Now, on more recent games this has been made much harder. You can load up a game save state file and change the amount of money you have from $1,000 to $1,000,000, for example. Game & File HackingĪnother popular reason you might use a hex editor is game hacking. If you see a filetype but have no idea what kind of program might be used to open that file, you might check out OpenWith which lists many file extensions and the programs used to open them.

Open the file in a hex editor, and it is immediately clear that this file is indeed a PDF file, and a quick switch to the file extension and you will be able to open it right up in Adobe Acrobat or other proper reader. When your system sees that extension, it will try to launch Microsoft Word to open the file - but it will fail. Now that we have the basics of hexadecimal out of the way, let's move on to some hex editors. Once you reach the end of the numeric "digits", you simply increase the number to the left by one, just like you do with the decimal counting system. Counting from 0 to 31 (converting from decimal to hexadecimal):Ġ 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F Instead of using digits 0-9, hexadecimal uses digits from 0 to F. The binary number system made up of 0s and 1s was invented by Gottfried Wilhelm von Leibniz.įinally in the 1950s or 1960s IBM formalized the Hexadecimal number system, which is a short way to represent binary data. Decimal was invented by the Persians about 6000 years ago.įast forward to 1679. The number system that humans use to count is called decimal, the numbers from 0 to 9. So how does hex work, what is a hex editor and why might you need to use one on your PC?

Yet being able to directly modify the raw bits and bytes in your computer can sometimes be used to your advantage. Although literally every file is stored on your computer in this format, you almost never see this data anywhere. The term hex, short for hexadecimal or base-16, is the raw data structure that all files stored on your computer follow.
