What you can do with Blitzer
Give file transfers a dedicated workspace. Add files or folders, select a destination folder or drive, and let Blitzer copy in parallel while checking what arrives. Follow progress in one clear view and keep your original files in place. A focused way to move project folders, media libraries and everyday files onto another drive. Adaptive parallel copying overlaps the work, while destination readback checks the result before completion.
- Add files and folders by choosing or dropping them
- Copy in parallel to a selected folder or drive
