# Your Cloudflare

What Cloudflare R2 is, and how Folder turns your R2 buckets into real folders in Finder, the Files app and the web. Your files never touch our servers.

Your R2 buckets as folders. Your files stay in your account.

## What R2 Is

Cloudflare R2 is object storage: buckets in your Cloudflare account that hold files. It speaks the S3 API, so tools built for Amazon S3 work with it, and Cloudflare Workers reach a bucket directly.

- No egress fees: reading your files out of R2 costs nothing per gigabyte.
- Two storage classes: Standard, and Infrequent Access for files you rarely read.
- A free tier every month on Standard: 10 GB of storage, 1 million Class A and 10 million Class B operations. See [what R2 costs](/guides/r2/pricing).

On its own, R2 is storage, not a folder: no app in Finder, no history of a file (an overwrite or a delete is final) and no share link with a password. Folder adds those, below.

## Connect

Sign in with Apple, then connect Cloudflare. On the first screen that is In Your Cloudflare; later, the web's folder list has Connect Cloudflare. You pick the buckets, and each one shows up as a folder in Finder, the Files app and on the web.

If you have no bucket yet, you can make one on the same page.

## What Folder Puts in Your Account

A few small workers, named `folder-*` and tagged, so you can see them in your Cloudflare dashboard. They give your buckets what R2 doesn't have on its own: versions, share links and invites. Uninstalling removes every trace.

Your files live in your Cloudflare account and we are never in the data path: the apps read and write your bucket through the workers in your own account.

## What It Costs

Your bill is Cloudflare's bill, usually $0. R2 storage is cheap and has no egress fees. Cloudflare bills you directly; we never see the bill. Signed in at folder.dev, Settings › Your Cloudflare › Usage, Costs and Updates shows what your folders keep there, old versions included, and this month at R2's list price.

## What You Get on Top of R2

- Every overwrite and delete kept and restorable. See [history](/docs/history).
- Share links with a password or an expiry, on your own account. See [share links](/docs/share-links).
- Invites that put the folder in someone else's Finder, with no Cloudflare login for them. See [invites](/docs/invites).
