What is TXT?
TXT (Plain Text) is the most basic and universal file format for storing text. It contains only printable characters with minimal formatting - just line breaks and basic spacing. No fonts, colors, or styling information is included.
Text files are extremely lightweight, portable, and can be opened by virtually any device or program. They're the lowest common denominator for text-based data exchange.

Technical Information
Text files use character encoding systems like ASCII, UTF-8, or UTF-16 to represent text. UTF-8 has become the standard as it supports international characters while remaining backward compatible with ASCII.
