Upload data

Back in the "S3" service, in your bucket's page, you can drag-and-drop your data directly from the browser into the bucket (or click the "upload" button).
Attempting to upload too many files this way can freeze or crash your browser. To avoid that, consider using one of the other methods described in the dataset section. To upload (and delete) bucket objects using these, you'll need write permissions.
