TeraCopy is an example of the freemium licensing model.

The author asserts that it has full Unicode support. TeraCopy can replace Windows Explorer's copy and move functions. It may skip copying for numerous reasons that the user could correct if they were known, such as a too-long file name. TeraCopy offers no explanation for skipped files it simply reports them as 'Skipped'. TeraCopy also shows failed file transfers and allows the user to fix the problem and recopy the problematic files. In case of transfer errors, TeraCopy will try several times after that, it skips the faulty file and proceeds with the rest of the operation. Asynchronous copy speeds up file transfer between two physical hard drives. TeraCopy uses dynamically adjusted buffers to reduce seek times. Its focus is data integrity, file transfer reliability and the ability to pause or resume file transfers. TeraCopy is a freemium file transfer utility designed as an alternative for the built-in Windows Explorer file transfer feature.
