: This is a fast hex editor rather than a traditional text editor. It is "amazingly fast" for viewing the raw binary data of large files like MKVs and uses very little memory.
: You can use tools to split the large file into smaller chunks (e.g., 50MB each). This allows you to use standard editors to inspect specific sections.
: If you are on a Unix-like system (or using WSL/Cygwin on Windows), running strings yourfile.mkv will extract all sequences of printable characters, which is effective for finding metadata or embedded subtitles without loading the whole file as a "text" document.
: Plugins like the Big Files plugin for Notepad++ allow you to view the file in small "chunks," preventing the application from freezing.
: These classic Unix-based editors are extremely efficient and can be tuned to handle large files rapidly, though they have a steeper learning curve.
