| Feature | Description | Practical Benefit |
|---------|-------------|-------------------|
| Dual‑Mode Copy Engine | Speed (parallel threads, buffer tuning) and Safety (checksum verification, resume support). | Lets power users squeeze every last MB/s out of SSDs while casual users can keep the “just copy” experience. |
| Pause/Resume & Queue Management | Drag‑and‑drop files into the queue, reorder, pause any job, or set “auto‑resume on power‑restore.” | Perfect for large migrations or intermittent network connections. |
| Error‑Handling Policies | Choose per‑job actions for “file in use”, “permission denied”, or “disk full” (retry, skip, rename, abort). | Saves you from endless pop‑ups when copying massive media libraries. |
| Transfer Log & Statistics | Real‑time graph of throughput, per‑file transfer time, and a CSV export of the session log. | Handy for IT admins who need to audit copy performance. |
| Advanced Plugins (Ultimate only) | • AES‑256 Encryption – encrypt files on the fly.
• Speed‑Limiter – cap bandwidth for network transfers.
• Smart‑Copy – detects duplicate files and offers hard‑link or symlink creation. | Extends the utility beyond plain copying, making it a lightweight file‑sync tool. |
| Theming & UI Customisation | Light/Dark themes, custom icons, and a “compact mode” that hides the detailed file list. | Integrates nicely with any desktop environment. |
| Cross‑Platform Consistency | Same feature set on Windows, macOS, and Linux (via the Qt framework). | Teams can standardise on a single tool regardless of OS. | The Context: What is Ultracopier

A key cannot turn the free version into Ultimate; you need the actual installer. buffer tuning) and Safety (checksum verification
