What is a .CFG file?
A .cfg file stores configuration settings for all kinds of programs and games.
- Did you know
- The .cfg extension is used everywhere from games to system tools for saved settings.
- There is no single .cfg standard - each program defines its own layout, though most stick to simple key-and-value lines.
- Because it is plain text, a .cfg can usually be tweaked by hand to change how an application or game behaves.
- What Analyser reads
- Identify configuration and small text files: TOML, INI, .env, CONF, CFG, Java properties, generic .config, info notes, .lst list/index files, and Windows Setup Information (.inf) driver/install scripts.
- Depth of analysis
- .CFG is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .CFG file
- Drag a .CFG file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
