OtterExplorer

OtterExplorer is the file browser in the web console. It lets you work with the contents of your buckets straight from the panel: explore prefixes as folders, upload objects (including large files via multipart upload), download them and delete them. It's the fastest way to take a look at a bucket or run a one-off operation without opening a terminal.

What you can do

• Browse folders: key prefixes are shown as a folder structure so you can walk the bucket naturally.
• Upload objects: drag and drop or pick files. Large files use multipart upload, which is more reliable and resumable.
• Download objects: grab any object in one click via a temporary, secure link.
• Create folders: organize content by creating new prefixes.
• Delete objects: remove files you no longer need.

How to access it

Open the console, go to the Buckets section and pick the bucket you want to inspect. Inside the bucket detail you'll find OtterExplorer, with the current path shown as breadcrumbs to move between folders.

Uploading files

Go to the destination folder inside the bucket and drag your files onto the upload area (or use the upload button). OtterStorage automatically decides when to use a simple or multipart upload: large files are split into parts and sent piece by piece, so a long upload is more robust against network drops. Since we don't charge for requests, multipart uploads add no per-operation cost.

Downloading and deleting

Each object can be downloaded through a temporary signed link that expires on its own and avoids exposing the object permanently. Deleting removes the object from the bucket; if the bucket has versioning enabled, a delete marker is created and previous versions are kept according to your configuration.

Permissions and security

• OtterExplorer respects your console session permissions: you only operate on your own buckets.
• Downloads use presigned URLs with expiry, not permanent public links.
• Bucket creation happens from the panel, not from the explorer (your access keys are scoped to a single bucket and can't create buckets).

OtterExplorer vs. an S3 client

OtterExplorer is ideal for interactive, one-off operations: checking what's in a bucket, uploading a specific file or grabbing something quickly with no setup. For bulk or automated tasks — syncing thousands of objects, scheduled backups, CI/CD pipelines — use an S3-compatible client:

• AWS CLI — the standard for scripting.
• rclone — efficient sync and copy.
• MinIO Client (mc) — a nimble command-line alternative.

Coming from another provider? With OtterMigration you bring whole buckets into OtterStorage with nothing to install, following progress from the console.
