TeraCopy replaces Windows copy and move operations with verified, resumable file transfers.
TeraCopy is a file copy utility for Windows 10 and Windows 11, with macOS also listed as a supported platform. After installation, its preferences let you choose whether it replaces File Explorer’s default copy handler; you can turn off that integration and start transfers manually instead. The freeware license is for home use, while commercial use requires a Pro or Business license.
How transfers work
Once configured, TeraCopy can take over ordinary copy, move, and drag-and-drop operations in File Explorer. It is designed to keep a job moving when individual files cause errors: problem files are skipped, the remaining files continue copying, and you can retry the failed files after the transfer finishes.
When a transfer is interrupted because a network share or USB device disconnects, TeraCopy can wait for the destination to return and resume the work. For an additional integrity check, TeraCopy can verify a copied file against its source using checksum algorithms such as CRC32, MD5, SHA1, and BLAKE3.
Queueing and files in use
Rather than running every copy job at once, the task queue processes multiple jobs one after another. This gives users with several transfer tasks a way to line them up without starting each operation separately. The free version is limited to two copy threads.
Some files cannot normally be copied while another process is using them. TeraCopy can handle locked files through an elevated service and Volume Shadow Copy, allowing those files to be included in a transfer. This is useful when a job needs to cover more than files that are currently idle.
Choosing the appropriate license
Home users can use the freeware edition, which includes checksum verification, queued transfers, error handling, and copying locked files. Organizations using the program commercially need a Pro or Business license. TeraCopy Pro also adds copying to several destinations, more threads, editable file lists, and favorite folders; these options are separate from the basic home-use feature set.
When it fits a copying workflow
The program is most relevant when transferring large folders to external drives, NAS boxes, or network shares, where a single failed file or temporary disconnection could otherwise interrupt a job. Its main practical benefit is transfer handling and verification, rather than a guaranteed speed increase: actual copy speed depends mostly on the drives involved.
For occasional transfers of a few small files, its queue and recovery features may be less important. For longer jobs, enabling Verify in the transfer window provides a way to check that copied data matches the source, while the option to retry only failed files avoids restarting an entire transfer because of isolated errors.
