Frequently asked questions

How do I use Folder Tree Generator?

Paste or drop your data into the workspace, adjust the options to fit your data, then copy or download the result. Turn a folder into an ASCII, Unicode, or Markdown tree with sizes.

Is my data uploaded or stored anywhere?

No. Everything runs locally in your browser — your data is never uploaded to a server. Nothing is sent to a server, so it's safe to use with private or sensitive data.

Is Folder Tree Generator free?

Yes — it's completely free with no account, no sign-up, no watermark, and no daily usage limits.

What's the maximum file size?

There's no hard limit imposed by the tool. Because processing happens in your browser, the practical ceiling is your device's available memory — most everyday files work instantly.

Do I need to install anything?

No installs and no extensions — it runs entirely in your web browser and even works offline once the page has loaded.
