What it’s for

Drivetrain copies footage from a card or drive to another location and proves every file arrived intact. Every file is checksummed after the copy. It never removes anything from the source.

Run a transfer

1. Source: drag a card, folder or drive into the left zone, or click to pick one.
2. Destination: drag or pick the folder to copy into. Turn on Keep folder name to create a folder with the source’s name inside the destination.
3. Speed: pick one of four presets.
4. Options: see below. The defaults are right for most offloads.
5. Start. Progress shows files copied, data moved, current speed and ETA.

When the copy finishes, verification runs automatically and the transfer turns green. Red means something didn’t match; the log tells you which files.

Speeds

Preset	When to use it
Steady	Warm or older spinning drives, long sessions, laptops on battery
Medium	Everyday offloads
Fast	SSDs and fast RAIDs
Cranked	NVMe and Thunderbolt, when you just need it done

Drivetrain detects the interface (USB 2/3, Thunderbolt, NVMe…) and shows it next to each location so you know what you’re working with.

Options

Option	Default	What it does
MD5 verify	On	Checksums every file after the copy. Slower, but the only way to be sure
Verify sizes	–	Faster check: compares file sizes only. Use for quick re-copies
Preserve dates	On	Keeps original modification dates
Extended attrs	On	Keeps macOS tags, Finder comments and other metadata
Skip existing	–	Don’t overwrite files already at the destination
Update newer	–	Only copy files that are newer than the destination’s
Delta sync	–	Copy only the parts of files that changed (for repeat copies)
Skip empty folders	–	Leave out folders with nothing in them
Exclude junk	On	Skips .DS_Store, Thumbs.db and similar
Exclude cache	On	Skips cache folders some cameras and apps create
Exclude proxies	–	Skips proxy files when you only want originals

Pause, resume, cancel

• Pause stops the copy cleanly; Resume picks up where it left off. Drives can cool down; nothing is lost.
• Cancel asks you to confirm. Files already copied stay at the destination.
• If a single file fails, you can skip it and continue.

History

Every transfer is logged: source, destination, files, data moved, time, speed, and whether it verified. Search the history to answer “did I copy card B on Tuesday?” months later. Totals (transfers, data moved, total time) are at the top of the page.

Notifications

With a Driver or Crew plan, Drivetrain can email or text you when a long transfer finishes or fails. Turn it on in Profile → Notifications; see Notifications.

Tips

• Copy one card at a time to a spinning drive; two at once is slower than one after another.
• Keep MD5 verify on for anything you’ll format the card after.
• For a second copy to an archive, use Cruise Control so it stays in sync by itself.
