You start copying a few hundred gigabytes, walk away, and come back to find one unreadable file stopped the whole transfer at 12%. TeraCopy is built for that situation. When it hits a problem file, it skips it, keeps going, and lets you retry the failures afterward.
Quick facts
- Version: 4.0.5
- Platform: Windows (a separate Mac version exists)
- Price: free edition; paid Pro/Business edition
- Free edition: up to 2 threads for copying, not licensed for commercial use
Key features
Skips problem files instead of stopping the whole transfer
If a copy error occurs, TeraCopy skips the problematic file and carries on. It also waits for a network or device to reconnect. When the transfer ends, you can retry only the failed or skipped files. You can also skip unneeded files by hand to shorten the job.
Checks that copies match the originals
TeraCopy verifies file integrity with 17 checksum algorithms (over 50 variations), including CRC32, MD5, SHA1, BLAKE3 and xxHash3. It can confirm that destination files are identical to the source. It can also generate and validate checksum files.
Copies files that are locked or in use
Using an elevated Windows Service and Volume Shadow Copy, TeraCopy can copy files that other processes have locked.
Handles unattended jobs
You can settle file-name conflicts in advance. In unattended transfers, a Skip All mode prevents interruptions. TeraCopy can also produce reports and run a PowerShell script when the job finishes.
A file list that doubles as the log
The list shows file names, sizes, source and target checksums, and any issues found. You also get a speed graph, counts of skipped or failed files, average speed and time remaining.
Queue transfers and review them later
Instead of running several copies at once, you can queue operations so they run one after another. TeraCopy keeps tasks and their file lists for a few days, so you can look back at them when troubleshooting.
Choose which metadata to copy
You can pick what travels with the files: timestamps, streams and permissions. You can copy only the folder structure, or apply only timestamps.
Works inside Explorer
TeraCopy replaces the copy and move functions in Windows Explorer, so you keep working as usual. An optional confirmation dialog for drag and drop helps you avoid dropping a folder in the wrong place.
Who it's for
It suits anyone who moves large folders, works with flaky external drives or network shares, or needs proof that a backup copy matches the source. The Pro/Business edition is the one to use at work, because the free edition is not licensed for commercial environments.
