Text Document

What is a TXT file?

A TXT file is a plain text document that contains unformatted text. TXT files store text without any styling, formatting, or special characters beyond basic ASCII or Unicode characters. They are one of the most basic and universal file formats, readable by virtually any text editor or word processor on any operating system.

More Information

The TXT format has been around since the earliest days of computing, predating most other file formats. It represents the simplest way to store textual information digitally. TXT files contain only printable characters and basic whitespace (spaces, tabs, line breaks), making them extremely portable and long-lasting.

Because TXT files contain no formatting information, they are often used for configuration files, data exchange, programming, and situations where simple text storage is needed without the complexity of rich text formats.

TXT File Characteristics

Content Type

• Plain text only - No formatting, fonts, or styles
• Character encoding - Usually ASCII, UTF-8, or other text encodings
• Line endings - Different systems use different line ending conventions
• No metadata - No author, creation date, or other embedded information

Encoding Standards

• ASCII - Basic 128-character set (English only)
• UTF-8 - Unicode encoding supporting all languages
• Windows-1252 - Extended ASCII for Western European languages
• ISO-8859-1 - Latin-1 character set

Best Practices

Creating TXT Files

• Use consistent encoding - Prefer UTF-8 for international support
• Consistent line endings - Choose appropriate for your platform
• Clear structure - Use spacing and indentation for readability
• Meaningful names - Use descriptive filenames

Content Organization

• Headers and sections - Use consistent formatting for organization
• Lists and bullets - Use dashes or asterisks for lists
• Indentation - Use spaces or tabs consistently
• Line length - Keep lines reasonable length for readability

Cross-Platform Considerations

• Test on different systems - Verify appearance across platforms
• Use standard characters - Avoid special or extended characters when possible
• Document encoding - Specify encoding when sharing files
• Convert line endings - Use tools to convert when necessary
