HexToolbox

That is a really yet another hex editor. It does open very large files very quickly and has no trouble working with them. Professionals may be conservative, and HexToolbox Hex Editor carefully retains the looks of DOS editors. At the same time, it makes editing as easy as possible. You can highlight separate bytes with colors and put bookmarks. The interface is quite handy: you can access most features without disrupting your work via the right-click menu. However, HexToolbox Hex Editor can open several files at once, but switching between them is not very convenient because you need to go to the Windows menu every time. Recommended to programmers.
