How to delete part of binary data from binary file? (hex dump). I tried GHex 3.18.0 binary file editor, but it's not suitable for this, just lack even simple features. For example, I need select the offset address range 0x83FFF0 – 0xDDAFEB, and delete the whole block (actually, delete part starting from 0x83FFF0 to the end of file). I prefer a GUI tool, because I need to see binary content anyway. However: first I can find addresses use GUI editor, then use some scripting command to modify file (possibly bbe commands?).
