Changelog

New

• NFSv4: NFS connections can now use version 4. Pick NFSv3 or NFSv4 in the connection settings on Mac, iPhone and iPad. NFSv4 needs only port 2049, so it works through firewalls and routers without the portmapper, and Driio handles servers that publish the export as the NFSv4 root for you.
• Keep Downloaded keeps the whole tree: on macOS 27 and later, pinning a folder now brings every folder beneath it, including ones added on the server afterwards. A file dropped into a subfolder you have never opened is downloaded and waiting, offline. Pins are budgeted so a pin on an enormous tree stops at a sensible line instead of filling your disk.
• Ready for macOS 27 and iOS 27: tested against both. The new pinning is built on the system's own eager-materialization support, which arrived in macOS 27.

Bug Fixes

• Deleted files could stay visible forever: when a lot of files were removed on the server at once, some could stay in Finder and the Files app for good. The change list is handed over in batches, and one batch carrying a later change moved the bookmark past deletions that had not been sent yet. On a real connection that left about 770 files that no longer existed. The bookmark can no longer skip anything, and the first launch after updating clears any leftovers already on your device.
• A folder you cannot read no longer breaks the whole connection: listing a folder your account has no access to was treated as the entire connection failing: uploads then silently did nothing until Driio was quit and reopened. Such a folder now fails on its own and everything else keeps working. Driio also checks every few minutes for a connection stuck in that state and reconnects it once the server answers.
• Moves the server refuses now snap back: a file or folder the server would not let you move stayed at its new location in Finder while the server still had it at the old one. It now returns to where it really is, and the reason is recorded in the connection's error history.
• Errors say what actually happened: an SFTP failure used to surface as an unreadable \u201cerror 1\u201d no matter the cause, which also meant a folder that could not be created reported success and the upload into it failed instead. Permission denied now says permission denied.
• Changing a password keeps your files: updating a connection's password rebuilt it from scratch, discarding everything already downloaded and re-reading the whole share. It now simply reconnects.

Improvements

• Office lock detection on by default, and on WebDAV: new connections detect Word, Excel and PowerPoint documents a colleague has open and show them as locked, so nobody overwrites anyone. It now works on Nextcloud and other WebDAV servers as well as SMB and SSH. Connections you already have keep whatever you set.

Bug Fixes

• Upload progress on iPhone and iPad: copying a new file into Driio in the Files app now shows a live progress ring and byte count. Before, it sat on “Waiting…” until the upload quietly finished, even though the transfer was running the whole time. Replacing an existing file was fixed in v2.6; this covers new files.
• Adding your first connection on iPhone: on a fresh install the + button did nothing until a connection already existed. It works from the very first tap now.

Improvements

• The menu bar matches Finder: connections you have disabled on this Mac no longer appear in the menu bar list, so everything you see there can actually be opened.
• The Dashboard tells you why: a connection you have disabled now shows as Disabled instead of Idle, and keeps its storage figures so you can still see what it is holding.

Improvements

• Lighter on your Mac: the Driio app is much easier on CPU and battery when you don’t have a window open.
• Deleting a connection cleans up properly: anything left behind by an earlier version is cleared next time you open Driio.
• Big connections are much faster: uploads to your biggest connections now run at the same speed as small ones, and removing a large folder went from the better part of a minute to a few seconds.
• Badges and locks keep up during a copy: file badges, Office lock markers and changes made on the server no longer wait for a big copy to finish.
• Housekeeping keeps running: Driio tidies its own records on schedule even on a connection that has been busy for days.
• Settings apply straight away: changing a connection’s settings no longer needs anything to restart first.

Bug Fixes

• Folders stuck on “Loading…”: a folder containing a shortcut back to itself sent Driio round in circles. It now spots the loop and steps around it.
• Slow uploads after renaming a folder: files dropped into a folder you had just renamed would sit and wait. They upload straight away now.
• Warnings that wouldn’t go away: a connection that dropped overnight stayed flagged long after the server came back. The warning now clears as soon as it reconnects.
• Storage showing as “Zero KB”: your biggest connections gave up before they finished counting. They now report properly.
• Damaged files after an interrupted upload: a transfer cut off part-way could be picked up again in a way that sent gaps to the server. The file arrived the right size but was not intact. Resume is now limited to cases where that cannot happen.
• Uploads giving up on a server hiccup: a temporary server error was treated as permanent, so the transfer was dropped instead of retried.
• Files disappearing from view: deleting something the server would not let you remove made it vanish and then reappear a moment later with no explanation, and an item the server no longer recognised could sit hidden indefinitely while Driio retried it. Both now leave the file where it is and say what happened.
• Dropbox uploads slowing themselves down: Driio was sending too many at once and getting throttled for it.
• Large files failing on iPhone and iPad: transfers above a certain size stopped with an error and could leave a duplicate behind. Driio no longer holds part of a file in memory while sending it, on Mac, iPhone and iPad alike. Fixed for every connection type.
• The wrong password message on iPhone and iPad: a connection missing its password told you to wait for iCloud to sync it, when the password simply needed entering again.
• Reclaims disk space: temporary working files from downloads, and Driio’s own internal records, were kept longer than they needed to be. Both are now cleaned up automatically, with any existing backlog cleared shortly after updating.
• OneDrive uploads that failed: a failed transfer left a half-open upload behind on OneDrive, still holding the place of the file it never finished. It is now cleared away when the transfer fails.
• No progress shown when replacing a file: saving over a file that was already there jumped straight to the uploading badge with no indication of how far along it was. It now shows progress, and can be stopped part-way.
• Changes made on the server right after you saved: a change arriving within a few seconds of your own edit was applied quietly, so the file on screen could be out of date until something else refreshed it.

Bug Fixes

• Improved Microsoft Office lock file handling: a document someone else has open in Word, Excel, or PowerPoint now opens read-only right away, however you get to it — and your own open documents no longer show as locked by someone else. Locks clear as soon as the other person closes the document.

When the Trial Ends

• Connections keep working: they stay in Finder, folders still open, and files still download — only changes to the server are paused. Before, the connection went quiet and its contents went stale.
• Finder and Files explain a refused change: saving, copying or renaming used to fail with a generic authentication error, which looked like a wrong server password. An alert now says the trial has ended and offers a button to the purchase screen. The same alert appears on iPhone and iPad.
• Copying files out is never blocked: an expired trial only pauses changes to the server. Getting your own files off it works either way.
• Notice before the trial ends: Driio sends a notification two days ahead, and again when it lapses, so it doesn’t just stop working while you aren’t looking. The menu bar shows how much time is left.

New: Notifications from Your Cloud Connections

See what’s happening on your cloud accounts without running each provider’s own app.

• On Dropbox and OneDrive, get a notification when someone shares a file or folder with you.
• On Nextcloud, see the same feed the official desktop app shows: shares, comments, mentions, and app notifications.
• Turn it on per connection with Show Notifications on This Mac in connection settings. It’s off until you ask for it, and the choice stays on the Mac you make it on. Clicking a notification opens the item on the provider’s website.

Improved: Much Lighter on Your Mac

On connections with a lot of files, Driio’s background sync could use enough CPU to spin the fans up and eat into battery. That’s fixed.

• Looking up a file used to mean checking every file Driio knows about on that connection — hundreds of thousands on a big one. It’s now instant, no matter how large the connection grows.
• Folders you haven’t opened in a while now go quiet instead of being checked at full speed forever. The folders you’re actually working in stay just as fresh.
• In our testing on a connection with about 650,000 files, background CPU dropped from a full processor core to under a tenth of one.
• This is easier on your servers as well. macOS re-reads folders for its own housekeeping, and Driio was mistaking that for you browsing, so folders you never opened stayed on the fast-refresh list day and night. Now only a real application counts as browsing, and an idle Mac sends a small fraction of the server traffic it used to.
• Driio’s internal bookkeeping had accidentally been flagged for Spotlight indexing, so every file it discovered or downloaded set off background indexing of values nobody could ever search for. Removing the flag also removed the constant CPU and disk writes that came with it.

Bug Fixes

• Folders open when you click them: some folders would sit on “Loading…” until you clicked away and came back.
• Ghost folders no longer keep Driio busy: a folder the server lists but can’t open is now set aside instead of being retried every couple of minutes forever. It comes back on its own once the server can open it again.
• “The file names may be out of date” after resetting a connection: resetting starts Driio’s record of that connection over, but macOS kept the position it had already reached — so it skipped that many files in the rebuilt connection and never went back for them. Driio now recognizes a reset and has macOS read the connection fresh.
• Files with a slash in the name open again: a name like Invoices 1/17.pdf could refuse to open, because servers store that character in different ways and Driio assumed one of them. Names now travel exactly as your server spells them. On WebDAV, a single one of these could take the whole connection offline until you reset it.
• Nothing to do on your side: existing connections correct themselves as you browse, or the first time you open an affected file. There’s no re-scan or re-download involved, and your connections stay put.
• Saving a file with a slash in its name works: on SMB shares and OneDrive, which cannot store that character literally, Driio now writes the name the way those servers expect instead of failing.
• A refused upload no longer multiplies: when a server permanently rejected a file, macOS kept retrying under name 2, name 3, and so on, and one file could leave hundreds behind. It now reports the problem once. Uploads that fail for a temporary reason, like a dropped connection, still wait and try again.

On iPhone & iPad

The filename fixes and the performance improvements apply everywhere Driio runs. Cloud notifications are macOS-only, because they run in the Driio menu bar app.

New: Live Updates from SMB Servers

When someone else changes a file on an SMB server, it now shows up in your open Finder windows within seconds, instead of waiting for the next refresh.

• Files created, changed, renamed, or deleted on the server appear in an open window within seconds, using SMB2 change notifications.
• Updates keep arriving even after macOS suspends Driio’s background helper, because the change watch runs in the Driio app itself.
• Servers that don’t support change notifications keep the familiar periodic refresh. Servers that accept a watch but never send anything (seen on some Samba setups) are detected automatically and fall back too.

New: Windows That Refresh Themselves

An open folder now keeps itself up to date even when you’re not touching it.

• A file added from your phone or another computer shows up in a folder you already have open, without clicking Refresh or navigating away and back.

Improvements

• Dropbox changes appear right away: a file added to Dropbox from another device now shows up without you having to browse to it first.
• The quick freshness check when you step into a folder Finder drew from its cache now runs on every connection type, not just some.
• Change detection now checks its own work: while updates keep arriving it eases off on background checks to stay light on the server, and the moment something slips past, it speeds back up. It’s never slower than before.
• Less background reconnecting for idle SMB shares.

Bug Fixes

• Fixed a data-loss bug when renaming a folder while files were still uploading into it. The folder could briefly disappear from Finder and the freshly uploaded files could be swept away and deleted. A rename now keeps the folder in place, any affected files are repaired instead of deleted, and the folder refreshes right away.

On iPhone & iPad

The live-update features in this release are macOS-only for now. On iPhone and iPad, Driio still picks up server-side changes on its regular refresh, because iOS limits how long a file provider can keep working in the background.

New: Share Files from Finder

Create share links and manage who has access to a file without leaving Finder. Right-click any file on a supported connection and you’ll find two new actions: Copy Share Link and Manage Sharing.

• Copy Share Link: create a public link to a file and copy it to your clipboard in one click. Works with Nextcloud, OneDrive, Dropbox, and Amazon S3. (S3 links are presigned and expire after 7 days.)
• Manage Sharing: see every share on a file (public links and the people or groups it’s shared with, marked view or edit), revoke any of them, or share with a specific person. Recipient search with email fallback, plus Allow-editing and Notify-recipient toggles.
• Sharing shows up only where it works: Driio checks each connection’s capabilities and hides the menu items on connections and files that don’t support it.
• A confirmation panel reminds you whenever a link makes a file publicly visible.

New: Share Links on iPhone & iPad

Sharing comes to iOS through the system Share sheet. Select a file on a supported Driio connection, tap Share, and choose Driio Share Link to create a public link and copy it in a single tap.

• Same connections as the Mac: Nextcloud, OneDrive, Dropbox, and S3.
• Lives in the Share sheet rather than the Files context menu. (On iOS the Files menu can’t tell Driio which item you picked; the Share sheet hands over the file directly, so it just works.)

Improvements

• Fresher browsing: the folder you’re looking at is checked for changes first on every refresh, and stepping into a folder that Finder drew from its own cache kicks off a quick freshness check, so changes made on the server show up sooner. Listings you navigate away from now cancel cleanly instead of tying up a connection.

Bug Fixes

• Fixed the Stop button in Files/Finder not actually cancelling a download. On SMB, Nextcloud/WebDAV, OneDrive, and FTP the transfer used to keep running to completion in the background. Cancelling now stops the download immediately on every protocol, with no leftover error, even when the file was being opened or previewed at the same time, which used to leave a stray “could not download” alert.
• Fixed quick folder-to-folder navigation on WebDAV and cloud connections occasionally dropping the connection with a spurious “Cannot Connect” banner. Clicking away from a folder before its listing finishes is normal, and is no longer mistaken for a connection failure.

New: Diagnostic Logging

When something goes wrong with a connection, you can now turn on detailed logging and send the resulting file when reporting an issue. Logging is off by default in release builds, and the log writes to the shared app group container so it survives between launches.

• Toggle on under Advanced → Diagnostics on macOS, or Settings → Troubleshooting → Diagnostics on iOS
• Off by default in release builds, so there’s no overhead until you turn it on

Improvements

• Clearer SMB error messages: connection and browse failures now explain what actually went wrong instead of showing a generic “The operation couldn’t be completed” alert. Wrong credentials, missing shares, permission denials, and unsupported protocol versions each get a specific message, and a server that only speaks SMB1 (such as legacy Samba) now says so instead of being misreported as a bad password. Lower-level network failures (connection refused, host unreachable, DNS, TLS) are reported honestly too.
• Automatic log rotation: the current log rolls over once it passes your size limit (default 10 MB), and older copies are dropped past the keep count (default 4 files), so logs never grow unbounded.
• View logs without leaving the app: Show Logs in Finder on macOS opens the logs folder, and Share Logs on iOS exports the current log and any rotations via the system share sheet.
• Less intrusive review prompt: the App Store review request now appears only after you’ve actually used the app, waiting for a first-use grace period, a few successful transfers, and a polite interval before asking again.

Bug Fixes

• Fixed SMB shares on macOS getting permanently stuck after a brief network problem. A single failed directory listing (a timeout, dropped connection, or a server briefly unreachable after sleep or a network change) used to disconnect the share in Finder with no retry. Transient failures no longer disconnect the share, and any share left stuck by an earlier version reconnects the next time you open Driio.

Bug Fixes

• Fixed large downloads from WebDAV (including Nextcloud) and OneDrive failing with a false “Transfer stalled - no progress for 30 seconds” error. The download was streaming at full speed the whole time, but the URLSession progress callbacks were being silently suppressed, so the stall watchdog never saw the byte counters. Affected any file that took longer than 30 seconds to download, regardless of network speed.
• Fixed chunked uploads to WebDAV (Nextcloud) and OneDrive falsely stalling on slow upload links. Per-chunk progress is now reported continuously instead of only at the end of each 5 to 10 MB chunk, so a single chunk taking longer than 30 seconds no longer fails the whole transfer.

New: OneDrive Support

Driio now supports Microsoft OneDrive. Your OneDrive files show up in Finder and the iOS Files app the same way every other protocol does.

• Uses the Microsoft Graph API (the same one the official OneDrive clients use)
• OAuth sign-in via Microsoft's identity platform. Your password is never stored.
• Tokens stored in iCloud Keychain and synced across your devices
• Chunked uploads for large files via Microsoft Graph upload sessions
• Available on both macOS and iOS

New: NFS Protocol Support (NFSv3)

Driio now supports NFS, the standard file-sharing protocol on Unix and Linux. Connect to exports from Linux servers, FreeBSD, Synology, QNAP, TrueNAS, and other NAS devices.

• NFSv3 protocol with connection pooling for parallel transfers
• Optional UID/GID override for AUTH_SYS authentication
• Available on both macOS and iOS

New: Network Restore Recovery

File Provider domains are now automatically recovered when your network connection is restored. If a connection drops and comes back, Driio re-registers it without manual intervention.

Bug Fixes

• Fixed deleted subfolders getting stuck on "Loading" in Finder. The polling registry now releases a folder's path as soon as it's deleted, so stale subtrees don't linger after a successful delete.
• Fixed SSH/SFTP uploads getting reported as "stalled" after they'd already finished. The transfer watchdog now gives the post-upload verification step its own budget and counts any progress callback as activity.

New: TLS Certificate Flexibility

Connections to self-hosted servers with self-signed certificates previously failed with an untrusted certificate error. A new "Allow Untrusted Certificates" toggle is now available for WebDAV, S3, and FTP connections.

• Toggle located in the Advanced section of each connection editor (macOS and iOS)
• Off by default. Turn it on only for servers you trust that use self-signed or private CA certificates.
• Setting syncs across devices via iCloud

New: SSH Host Key Verification

SSH connections now verify the server's identity on every connect. Same Trust-on-First-Use model OpenSSH uses.

• First connection captures the server's host key fingerprint automatically
• Subsequent connections verify the fingerprint. If the server's identity changes unexpectedly, the connection is blocked.
• Verified fingerprint is shown in the connection editor and syncs to all your devices via iCloud
• Existing connections verify on next save. A notice in the editor flags any connection that hasn't been verified yet.

Fix: FTP Certificate Verification

FTPS connections now verify server certificates by default, matching the behavior of all other protocols. Previously, certificate verification was skipped unconditionally for FTP.

New: iOS Support

Driio is now available on iPhone and iPad. Your connections appear in the Files app just like on Mac.

• Browse and manage files on SMB, SSH/SFTP, WebDAV, FTP, S3, and Dropbox from the iOS Files app
• Per-device connection control. Disable connections that only work on your local network so they don't clutter your phone.
• Internal network detection. Connections to private IPs get labeled "Local Network" so you know which ones won't work away from home.
• Error history. The last 10 errors per connection are kept around so you can diagnose without digging through logs.

New: iCloud Sync

Connections now sync across all your devices automatically via iCloud.

• Add a connection on your Mac and it appears on your iPhone (and vice versa)
• SSH keys sync via iCloud Keychain. Generate once, use everywhere.
• Passwords and OAuth tokens sync via iCloud Keychain
• Per-device enable/disable is intentionally NOT synced. Each device controls its own set.

Improvements

• Faster startup: deferred keychain diagnostics and iCloud sync off the main thread
• Better Finder integration: credential changes now automatically reset the File Provider domain so Finder picks up the fix immediately
• SSH key manager: shows a clear warning when a private key is missing instead of silently failing
• OAuth sign-in: completing sign-in now persists immediately without needing to hit Save
• App launch: clicking the app icon now always shows the main window, even when running as a menu bar item
• License check: the dashboard loads first while StoreKit resolves entitlements
• Connection pool stability: fixed shutdown hangs, WebDAV idle connection leaks, and enumerator cache cleanup

Bug Fixes

• Fixed "Syncing Paused" deadlock in iOS Files app
• Fixed iCloud connection deletion sync (was additive-only, never removed deleted connections)
• Fixed SSH key sync issues across devices
• Fixed connection pool shutdown hangs and WebDAV idle connection leaks
• Fixed credential warning banners appearing on new unsaved connections

New: Dropbox Support

• Browse, download, upload, and manage Dropbox files directly in Finder
• Real-time change detection via Dropbox longpoll, with configurable fallback polling
• Chunked uploads for large files

Improvements

• Added local storage usage display to the Activity Dashboard
