Driio puts your servers in the Files app. SMB shares, SFTP servers, NAS drives, WebDAV, Amazon S3, NFS, Dropbox and OneDrive appear next to iCloud Drive, and every app on your iPhone and iPad can open, save and share files on them. ONE JOB, DONE PROPERLY Driio doesn't scan PDFs, edit photos or play video. It connects your storage to the Files app you already use, so every app's open and save screens reach your NAS and servers without another app in the way. EIGHT WAYS TO CONNECT • SMB: Windows shares, Synology, QNAP, TrueNAS, Unraid and Samba servers • SSH/SFTP: password or Ed25519 key authentication, with keys generated in the app • FTP and FTPS • WebDAV: Nextcloud, ownCloud and web hosting • Amazon S3 and S3-compatible storage: MinIO, Backblaze B2, Wasabi • NFS: NFSv3 and NFSv4 • Dropbox • OneDrive MADE FOR ON THE GO • Driio flags connections that only work on your home or office network • Turn connections off per device to keep the Files app tidy • Share links for Dropbox, OneDrive, Nextcloud and S3 from the Share sheet • Recent errors listed per connection, so you can see what went wrong PRIVATE BY DESIGN • Direct connections only: your files never pass through our servers • Passwords and SSH keys stored in iCloud Keychain, synced end-to-end encrypted • No analytics, no tracking ONE SUBSCRIPTION, EVERY DEVICE Set up a connection once and it appears on your iPhone, iPad and Mac. • 7-day free trial • Monthly, yearly, or a one-time lifetime purchase Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdasla/
