Description
Access your S3 storage directly from the Files app, Finder, and other applications on iPhone, iPad, and Mac. Developed by the creator of Working Copy, this application provides seamless integration with S3-compatible storage services.
Once configured, S3 buckets appear alongside other cloud storage providers, with files available on demand. Files are downloaded as needed and automatically synchronized back to S3 when modified.
The app supports a wide range of S3-compatible services, including AWS S3, BackBlaze B2, CloudFlare R2, DigitalOcean Spaces, MinIO, and others.
Files and directories can be uploaded through the system share sheet on iOS and the Services menu on macOS. The app remembers preferred upload destinations for different file types, streamlining file management.
Pre-signed sharing links can be generated directly from Finder and the Files app, allowing temporary access to files for up to seven days.
Support for server-side encryption with customer-provided keys (SSE-C) and client-side AES-GCM encryption compatible with the Amazon S3 Encryption Client.
Comprehensive support for Shortcuts automation enables operations such as listing, downloading, uploading, and moving files.
A Pro Unlock is required for most features, available as a one-time purchase or a monthly subscription, with access shared across iPhone, iPad, and Mac. A one-week free trial allows users to evaluate the app before purchase.
What’s New
Version 2025.7
Support for Client-Side-Encryption. Keys are generated in Settings just like SSE-C keys.
Each file is encrypted with a unique key that is itself encrypted with the master key. The encrypted file and encrypted/wrapped key is stored on S3 and decrypted locally as you download. This is compatible with Amazon S3 Encryption Client using wrapped AES-GCM encryption.
Browsing inside S3 Files can be handed-off to nearby iPhones, iPads or Macs signed into the same iCloud account.
Open in-app browser from context menu in Finder or Files app.
Ratings and Reviews
Finally, thank you
I basically gave up on having a mobile client like this since I’ve no time to make it. Just like Anders’ other apps. They’re just so well done, and like someone else said, it was an instant purchase when I saw it.
Anders, I don’t know if it matters for your sake, but the account you used for this app is different from ShellFish/Working Copy, I know for me I browse that way a lot (“this app is great, what else do they make”) but you also promote in the apps so it may not hurt.
Update
I got the app for my iPad and Mac. Everything was fine. Something weird was happening with my Mac, and I finally decide to start clean. I do a fresh clean install of MacBookPro. It's a 2017 MacBookPro with an Intel i7, 16gb of ram. It woks great. I go to reinstall this app, including the ShellFish app. Both can't install now. Apple, decided that my 2017 MacBookPro, including how powerful it is, is not worth updating to Montery. When I try to install S3 Files and ShellFish it states that I must update to Montery. However, Apply won't let me. So the apps are now useless. I'm done with Apple. From how they won't allow you to repair your stuff, to making it that after so many years that your equipement is useless to any new application when it's still powerfull enough to support it. To, how they treat developers and take 30%. I done with Apply! Middle finger to you Apple. I don't need Apple any more. Moving to Linux. Sick of Apple!!!!
Fantastic Application with a Great Developer
I don't write reviews but when such an app comes into my life, it needs to be done. This app is everything I need and more to make S3 my new cloud storage at a fraction of the cost of other options. Between deep glacier for archives and instant access in files for more immediate, I am very very pleased! The lifetime purchase and lack of tracking in the privacy label is just a cherry on top! Don't hesitate, get this app today!
