Introduction

If you use Cloudflare R2 for object storage, you may want to upload files that are larger than 300 MB. The Cloudflare Dashboard doesn't allow this, however you can use any third party app that is compatible with the Amazon S3 API. CyberDuck works for me, so here's the steps for how to use it with R2 to upload files larger than 300 MB.
