ayi <t>Free read-only viewers:<br/> <br/> Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.<br/> <br/> klogg (Windows, macOS, Linux) – A maintained fork of glogg.

But from a UI standpoint, it's rather minimal.<br/> <br/> LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.<br/> <br/> Lister (Windows) – Very small and minimalist.

Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (4 GB) files, assuming you have the RAM<br/> <br/> (Réponse tronquée)</t>
