The S3 desktop client for Mac, Windows, and Linux.
Mount any S3 bucket — or any S3-compatible service — as a native drive on macOS, Windows, and Linux. IAM roles with short-lived credentials, bucket-scoped mounts, pre-signed URLs, and five S3-compatible providers in one connector.
— What you get
S3 at the depth serious users need.
Buckets as drives.
Every bucket you can access shows up in Finder, Explorer, or your Linux file manager. Open files in any app — Photoshop, Office, Premiere — and save back to S3 directly.
IAM roles + STS + MFA.
Skip long-lived access keys. ExpanDrive can assume an IAM role via STS for short-lived credentials, with MFA prompt support at connect time. The most secure desktop S3 auth available.
Bucket-scoped mounts.
Mount a single bucket, a sub-path of a bucket, or the entire account. ACLs, bucket policies, and versioning all flow through. Secret keys stay in your OS keychain.
— Power features
Built for the way S3 is actually used.
Storage class and versioning.
View the storage class of every object, restore previous versions through the right-click menu, and copy pre-signed URLs for objects in a single keystroke. The S3 operations you actually use, surfaced in the file browser.
5 S3-compatible providers in one connector.
The same Amazon S3 connection setup works with DreamObjects, DigitalOcean Spaces, Akamai Linode Object Storage, OpenStack Swift, and Rackspace Object Storage. Point the endpoint at your provider; everything else is the same.
Bucket policy and ACL aware.
If a bucket policy restricts you to specific objects or prefixes, ExpanDrive respects it. Mount permissions inherit from your IAM user — ExpanDrive can't do anything your credentials can't.
— Cross-platform
S3 on every OS your team uses.
macOS
Built on the Apple File Provider extension. Buckets appear in Finder and ~/Library/CloudStorage. Native on Apple Silicon — no kext, no reboot.
Windows
Each bucket gets its own drive letter (user-selectable). Signed MSI installer for Intune / SCCM / GPO deployment.
Linux
Native .deb and .rpm packages with signed apt and yum repositories. Buckets mount at standard mount points and work with every Linux app — including dev tools and CLI workflows.
— Other S3-compatible storage
Same connector. Other clouds.
The S3 connection setup works against every major S3-compatible provider. If you're shopping cheaper egress, more storage tiers, or specific compliance posture, here are the siblings.
