Which file IO did you mean? https://www.espruino.com/Reference#File or https://www.espruino.com/Reference#Storage ?

I believe it's possible with Storage (even if not documented) but with File you'd just have to keep track yourself

I'm afraid there isn't anything - you'd just need to keep track yourself

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here

Just like Github, a blank line must precede a code block.
