If your goal is to extract readable text or specific data patterns from the MKV binary:

: Plugins like the Big Files plugin for Notepad++ allow you to view the file in small "chunks," preventing the application from freezing.

: 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.

: Specifically designed for large file handling, it can open and edit files well over 4GB by loading only small segments into memory at a time.
