I am searching for a free hex editor. Now, before you flag my question as a duplicate of “Free Hex Editor that Supports Chinese Characters” or “Hex editors for Windows?”, let me tell you that my question differs from those two questions in that I am searching for a hex editor with certain features. Secondly, the referenced questions and their answers are quite old. Maybe there is newer software that hasn’t yet made it into the older answers.
The hex editor I am searching needs to be capable of editing huge files (including disks, their partitions/volumes, and images thereof). I also need a structure viewer capable of displaying and editing data structures (declared in some kind of scripting language) in a human-readable way. Lastly, the hex editor needs to be free (not necessarily open-source).
Are there any hex editors fitting these three criteria?
I very much like 010 Hex Editor and “Free” Hex Editor Neo, but they are not free (the latter only has a structure viewer in the paid editions); Hexinator/Synalyze It has the same problem as “Free” Hex Editor Neo; HxD, Freeware Hex Editor, NPP+HexEdit, PSPad all don’t have a structure viewer as far as I know, WinHex is not free, and UltraEdit (which according to their website is “tHE wOrld’s Best teXt EDitoR” despite Vim’s existence) is neither free nor does it have a structure viewer (as far as I know).
The only free hex editor I found featuring a (read-only) structure viewer was frhed, but after installing it and reading the section about template files in its manual, it seems to me that the data structure functionality is very limited, nowhere near the structure viewers of 010 Hex Editor or “Free” Hex Editor.
Am I out of luck? Are there actually no free hex editors with structure viewers?
