AWS S3, as an organizer see empty bucket
Does the bucket have versioning enabled? You should be able to see it in the bucket properties: Versioning: enabled. If so, when you are looking at the empty folder, at the top there is a switch &quot;show versions&quot;, switch it on. Do you see some objects with hashes?
Try to delete them. Be careful, there are versions and &quot;delete markers&quot;, you have to delete both in order to completely empty the bucket.
Another option: you are billed for requests and data transfers https://aws.amazon.com/s3/pricing/?nc=sn&amp;loc=4
If something is checking the bucket rapidly, it can generate some costs.
But most often the delete versions is the reason.
