Ultracopier is file copying application software for Windows, macOS, and Linux. It is based on and supersedes SuperCopier.⁶ SuperCopier and Ultracopier differ mainly in terms of appearance. SuperCopier essentially serves as a skin for Ultracopier, with slightly higher CPU usage. SuperCopier typically refers to SuperCopier 3 and earlier versions, while Ultracopier refers to SuperCopier 4 and later versions, now known as Ultracopier 1.4.⁷⁸

Features include:¹

• Pause/resume transfers
• Dynamic speed limitation
• On-error resume
• Error/collision management
• Data security⁷
• Intelligent reorganization of transfer to optimize performance⁷
• Plugins

The application is distributed in standard and ultimate variants:

• The underlying source code is identical across editions and is published under the same copyleft license.
• The ultimate variant bundles alternative optional interface and engine plugins.
• Both distributions operate without DRM (as explicit restrictions are prohibited by the GPLv3 license) and can be redistributed freely by users.⁹

Ultracopier has been covered and reviewed by several independent technical publications. In an extensive performance evaluation by gHacks, the software was noted for its customizable performance tweaks, granular copy-engine settings (such as strict retention of file rights and timestamps), and plugin extensibility, though real-world transfer throughput gains depended heavily on specific hardware and drive arrays.¹⁰

Technology portal Gizmodo highlighted the application's unique advantage over default desktop environment dialogs when manipulating mass media directories or network storage pools, specifically praising its localized error-handling routines, which allow unassisted processing pipelines to bypass corrupted blocks or prompt user intervention instead of triggering a complete operation crash.¹¹ Platform profiles on systems repositories like Slashdot similarly classify the utility as a highly configurable power-user alternative for managing dense cluster transfers or unassisted backup workflows.¹²
