AXE is a hex editor/analysis tool that combines a rich GUI with powerful features. With the AXE editor you can cut, paste, drag, drop, undo, use Unicode, set bookmarks, jump, goto, find, replace, open multiple views, mark regions, and zoom. With AXE's analytic facilities, you can define structures, run scripts to transform or find data, use arithmetic on regions, diff, and more. AXE works on arbitrarily huge files, disks, and memory.
