S3: Cloud Storage is a fast, clean file manager for object storage. Connect Amazon S3 or any S3-compatible service and manage buckets and files right from your phone.

WORKS WITH
Amazon S3, Cloudflare R2, Yandex Object Storage, Selectel, VK Cloud, Backblaze B2, Wasabi, DigitalOcean Spaces, Google Cloud Storage (HMAC keys), MinIO and any other S3-compatible endpoint, including self-hosted servers on your local network.

CONNECTIONS
• Ready-made presets: pick a provider and the endpoint and region are filled in for you
• Path-style or virtual-hosted addressing, custom regions
• Keys limited to one bucket are supported: just set the bucket name
• Test the connection before saving
• Automatic switch to the right AWS region of a bucket

BUCKETS
• List, search, create and delete buckets
• "Empty and delete" for buckets that still contain files

FILES AND FOLDERS
• Folder navigation with breadcrumbs, pull to refresh, fast paging through large folders
• List and grid views with image thumbnails
• Sort by name, date or size, folders first, search in a folder, show or hide dot files
• Create folders, rename and move files and whole folders
• Multi-select with a long press: download, move or delete many items at once
• Object properties: size, type, date, ETag, storage class and custom metadata
• Built-in preview for images and text files, or open a file in another app

UPLOADS AND DOWNLOADS
• Upload from files, from the gallery (several photos and videos at once) or straight from the camera
• Background transfers with progress and speed, a queue with adjustable parallelism, cancel and retry
• Large files are uploaded in parts (multipart upload): if the connection drops, only the failed part is sent again
• Save downloaded files to any folder on your device or share them

SHARING
• Create temporary links (presigned URLs) to any file and copy or share them
• Choose how long links stay valid, from 1 hour to 7 days

PRIVACY
• No account, no ads, no analytics
• Secret keys are kept in the secure Android Keystore
• Requests go directly from your phone to your storage, never through our servers

ALSO
• Light, dark and system themes
• English and Russian interface
• Phone and tablet layouts
