A plain text file is one of the most portable surfaces the string ends up on. It is a line of characters, an encoding, an end of line and a filename. Nothing else. What each of those four parts holds decides what the file keeps and what the file loses.

What it is

A .txt file with a nexus market url in it is exactly what it says. The reader opens a text editor, types or pastes the string on one line, hits save, and closes the editor. The file is now a single line in a filesystem, in whatever character encoding the editor used, ending in whatever line separator the editor picked.

A plain text file is not the same object across operating systems, even when the visible line is the same. The end of line on one system is one byte and on another is two. The encoding on one editor is UTF-8 without a byte order mark and on another is UTF-8 with a mark. A reader who moves the file from one machine to another may find the string reads the same and the file bytes read differently.

Lifeline

  1. Not on the disk
  2. One line in a .txt
  3. Synced, moved or overwritten

What the file keeps

  • The characters exactly, because plain text does not autocorrect and does not apply hidden formatting like a rich text editor does.
  • The order of the characters, because a line in a text file is a run of bytes and the run is preserved by any tool that reads text.
  • The modification time, because the filesystem stamps it, and the reader can check it against their own memory of when the line was written.
  • The ability to grep for the string across a folder, because the file is just text and every text tool speaks it.

What the file loses

  • The privacy of not being on a network, because a lot of text files end up in cloud sync folders without the reader noticing until the file appears on another device.
  • The invisibility of trailing whitespace and hidden line terminators, because a .txt happily stores a space and a return at the end of the line and never shows the reader either of them.
  • The ability to prove nothing else edited the file, because a file with the wrong modification time still opens the same and a filesystem does not sign what it saves.
  • The link back to why the reader saved it, since the filename is the only handle and a filename like notes.txt says nothing about what is inside.

The invisible characters

A plain text file is exactly right until it is not. A paste that came from a chat may have a trailing newline. A paste that came from a rich text editor may have a non breaking space where a regular space used to be. A paste that came from a web page may have a zero width space between two characters that look adjacent. A reader who opens the file and sees the line looks correct is not looking at all the bytes on the line.

The single check the reader can do without installing anything is to move the caret one column at a time along the line, counting keys. If the line reads as 60 visible characters and the caret takes 61 steps to reach the end, one of the bytes is not visible.

What the filename says

The filename is not part of the string. A filename like nexus.txt is a signal to anyone reading the disk that the file is about nexus market. A filename that says nothing about the contents is safer for that reason, and worse for the reader who cannot remember which of a dozen text files holds the address. A dossier on this surface does not choose for the reader. It notes the tradeoff.
