Supercopier 5 -

We tested Supercopier 5 against Windows 11 (22H2) Explorer and TeraCopy 3.9 on a mid-range system (Intel i5-12400, 16GB DDR4, Source: 4TB 5400RPM HDD, Destination: 1TB NVMe Gen4).

Test Scenario: 200GB mixed data (50,000 small photos + 5 large ISO files).

| Tool | Time (Minutes) | CPU Usage (Avg) | RAM Usage | Success Rate | | :--- | :--- | :--- | :--- | :--- | | Windows Explorer | 47:32 | 8% | 890 MB | Crashed once on a long path name | | TeraCopy 3.9 | 41:15 | 5% | 340 MB | Completed, but slowed down on small files | | Supercopier 5 | 38:01 | 12% | 1.2 GB (caching) | Completed, no errors | Supercopier 5

Verdict: Supercopier 5 was 20% faster than native Windows on this mixed workload. The increased RAM usage (1.2GB) is intentional for caching and is automatically released when the copy finishes.

While Windows Explorer cancels the entire operation when it hits a single corrupted PDF, Supercopier 5 offers granular control: We tested Supercopier 5 against Windows 11 (22H2)

Because Supercopier 5 is open source, the code has been audited by the community. Version 5 does not:

All operations are local. The only network activity is checking for updates (which you can disable in settings). All operations are local

No software is perfect. As of the current release candidate (5.0.0.8), there are a few issues users have reported:

In the age of NVMe SSDs, Thunderbolt 4, and multi-gig internet, one would assume that Windows’ native file copying system has finally caught up with modern hardware. Yet, anyone who has tried to move a folder containing 50,000 small XML files or a 100GB virtual machine image knows the truth: the default Windows Explorer (especially the old Win32 version) is prone to stuttering, unexplained pauses, and the dreaded "discovering items" lag.

Enter Supercopier 5. For over a decade, the Supercopier project has been the go-to replacement for Windows’ file management engine. But with version 5, the developers have promised a complete architectural rewrite. Does it deliver? This article dives deep into the features, performance benchmarks, security, and usability of Supercopier 5 to see if it deserves a permanent spot on your taskbar.
