Teracopy 3.17 Final

If you are currently on TeraCopy 2.x: Yes, absolutely. The Unicode support, long path handling, and modern UI in version 3.x are worth the upgrade. Version 2.x is deprecated and will eventually break on Windows 11 updates.

If you are on TeraCopy 3.14 or 3.15: Yes, cautiously. Version 3.17 Final fixes a rare memory leak present in 3.15 when copying millions of tiny files. It is a stable release.

If you have never used TeraCopy: Download it now. Within one hour of using it, you will wonder why Microsoft hasn't bought this company and integrated it directly into Windows. TeraCopy 3.17 Final

The claim that TeraCopy is "faster" is nuanced. For a single, massive file (like a 20 GB ISO), TeraCopy is roughly equivalent to Windows Explorer. The bottleneck there is the physical speed of your SSD/NVMe drive.

Test Scenario: Copying C:\Windows\System32 (approx 8,000 files, mixed sizes) to a secondary SATA SSD.

The 25-30% speed increase is standard for fragmented, small-file transfers.
