Traditional editors (Notepad++, VS Code) try to load the entire file into RAM. If a file is larger than your available memory, the application crashes. Log Voyager acts like a video streaming service but for text: It creates a virtual map of the file. It reads only a tiny buffer (50KB) corresponding to the scrollbar position. When you scroll or jump, the old buffer is discarded, and a new one...
