Free means free: the full transfer engine, verification, journal, and history — no trial timer and no locked features. There is no catch; Copy Transit exists because file transfers deserved better tooling.
Copy Transit keeps a persistent journal of every job on disk. When you reopen the app or reconnect the drive, it discovers the interrupted job, classifies it, and offers to resume. Files that already completed and verified are skipped; only missing, partial, failed, or changed files transfer again. In-progress files live under temporary partial names, so nothing half-copied ever sits in your destination looking finished. On network shares, a dropped connection auto-pauses the job and it auto-resumes when the volume comes back.
You choose the level per job: Off (fastest), Size, Size + timestamp, SHA-256 (bit-perfect), or a checksum Manifest across the whole set. Size checks are effectively free. SHA-256 reads the destination back to hash it, so it adds time proportional to the data — worth it for client deliveries, archives, and backups. A file is only ever labelled Verified when the check you chose actually ran and passed.
During a move, Copy Transit never deletes a source file until its destination copy is complete — and has passed verification when it’s enabled. If anything fails mid-move, your sources are untouched.
Copy Transit stops and asks, or follows the conflict rule you chose for the job: keep both, skip, replace, or a relative rule like keep newer, older, larger, or smaller — with apply-to-all. It never overwrites an existing file unless you explicitly picked a rule that allows it.
No. Cancelling keeps every file that already committed to the destination. Only the single in-flight partial file is discarded, and the source is never touched by a cancel.
Yes — any volume your computer can mount works as a source or destination: SMB shares, external SSDs, SD cards. iCloud or File-Provider placeholders are downloaded first automatically before copying. Network resilience auto-pauses on a confirmed connection loss and auto-resumes safely.
Both. Select multiple sources — local, server, or cloud — and merge them into one destination as one job, or fan a single source out to up to five destinations, each queued, verified, and journaled independently. Fan-out applies to copies; moves keep a single destination by design.
macOS doesn’t allow apps to replace Finder’s built-in copy engine, and Copy Transit uses no hacks or private APIs. Instead it integrates the supported way: a Finder Quick Action, Services, Shortcuts, drag & drop, and — if you opt in — real ⌘X / ⌘V cut & paste of files through the safe engine, active only while Finder is frontmost. Everything else on your Mac keeps native copy/paste, untouched.
Your transfer journal, logs, and reports live on your device and stay there. File names, paths, contents, checksums, and transfer history never leave your machine. Anonymous, path-free crash summaries and coarse counters help fix bugs, and you can switch them off in Settings at any time.
macOS 13 Ventura or later on Apple silicon and Intel. The Windows edition (Windows 10 & 11, x64) is in early access and shares the same safe-engine design. Your history is preserved across updates on both platforms.
