TXT and RTF explained
Plain text is characters and nothing else — no fonts, no sizes, no layout. It is the most durable digital format there is, readable by every computer built in the last fifty years.
RTF is a plain-text markup format for styled documents. Opening one in a text editor shows readable markup, which makes it unusually durable — but it supports only basic formatting.
