Description of the Issue
Add a hex editor for large file for boost the read speed,
I compare HxD or notepad++ to open a 10G file, the first take 1s and the last crash, my wish:
00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F <- using scroll to get progress of a file, limit 0x10 is fine, where we roll, where using ReadFile to view, left view control hex-bytes and the right shows ascii or utf8 or other text.
we do not need alloc so much memory for once in this situation, just for read I think.
Describe the solution you'd like.

Research direction
No files, tests, or existing entry points are named. Start by locating the large-file opening and viewing path, then assess how a ReadFile-based hex and text view with scrolling would fit. Done means large files can be browsed without allocating the whole file and show hex bytes alongside text.
