In addition to the powerful editing functions, FlexHEX includes the unlimited Undo/Redo list, so there is no risk of losing work because of a typing error.

FlexHEX offers a rich set of navigation and tracking functions for browsing data. The bookmarks, the area lists, the jump history, and other convenient tools make inspecting binary files easy and straightforward.

Software professionals will like handy tools for string and GUID search, checksum computation, random number generation, and browsing COM classes. The advanced stream comparison function efficiently locates matching blocks in any binary data source, be it files, drives, or alternate streams.
