What is the difference between an .md file and a .txt file? MD file are documents that consist of plain text and use the Markdown syntax for formatting. MD files may include headers, lists, links, tables, and even pieces of codes. TXT files, meanwhile, usually store unformatted texts. The advantage of Markdown files is that they are very convenient to use when writing documentation, in software development projects, for notes, and for future conversion into HTML. While both types of documents can be edited in a simple text editor, Markdown editors can understand the special syntax and present texts accordingly. https://dataqix.com/markdown/
