lfhex (Large File Hex Editor) is a hex editor with paged input/output for viewing and editing files which are too large for system memory. Features include infinite undo/redo, search capabilities, a conversion dialog, scalable working area (sane resize), fast load times, fast save times, and a binary graphical diff/compare UI. It only takes an additional ~1.4 MB to open a 2 GB file, and can graphically compare 4 GB files using less than 15 MB of additional system memory.
