title: TiddlerFiles modifier: JeremyRuston tags: internals Tiddlers can be stored in text files in several different formats. Files containing single tiddlers can also have an auxiliary `.meta` file formatted as a sequence of name:value pairs: ``` title: TheTitle modifier: someone ``` !! ~TiddlyWeb-style .tid files These files consist of a sequence of lines containing name:value pairs, a blank line and then the text of the tiddler. For example: ``` title: MyTiddler modifier: Jeremy This is the text of my tiddler. ``` //The ContentType `application/x-tiddler` is used internally for these files// !! TiddlyWiki `
` .tiddler files Modern `*.tiddler` files look like this: ```
Note that there is an embedded 
 tag, and line feeds are not escaped.
	
And, weirdly, there is no HTML encoding of the body.
``` These `*.tiddler` files are therefore not quite the same as the tiddlers found inside a TiddlyWiki HTML file, where the body is HTML encoded in the expected way. Older `*.tiddler` files more closely matched the store format used by TiddlyWiki at the time: ```
This is an old-school .tiddler file, without an embedded <pre> tag.\nNote how the body is "HTML encoded" and new lines are escaped to \\n
``` //The ContentType `application/x-tiddler-html-div` is used internally for these files// !! ~TiddlyWeb-style JSON files These files are a straightforward array of hashmaps of name:value fields. Currently only these known fields are processed: `title`, `text`, `created`, `creator`, `modified`, `modifier`, `type` and `tags`. //The ContentType `application/json` is used internally for these files// !! TiddlyWiki HTML files TiddlyWiki HTML files contain a collection of tiddlers encoded in `
` format. //The ContentType `application/vnd.tiddlywiki2` is used internally for these files//
