Groovy Hex Editor is a tool for editing binary formats. I've paid particular attention to making it colorful and easy to use and tried to give it a cool looking color scheme (hence the name "groovy" hex editor). You can also downgrade it to a "standard" windows color scheme if thats more to your liking. It's a fully functional hex editor with many advanced features. You can toggle the display between hex and decimal, and there is a built in inspector that easily lets you see the hex, decimal, and binary equivalents of a group of bytes at once. You can easily control the number of bytes displayed per line, and the number of bytes per group. This makes it excellent for viewing various data types (bytes, words, long words, etc). The program features multi-level undo and redo features that let you quickly fix mistakes. There's even a changelog that lets you keep track of what modifications you've made to the current file. The main window is color-coded (and configurable) so that you can highlight different items in different colors. Various Werkzeuge are built in, including a string sifter feature that automatically pulls all of the ascii strings out of the file, so that you can see all the strings in one convenient place. This program features the SB-Software no-hassle guarantee: no spyware, no adware, no viruses, no expiration, and no disabled features.
