RoboExtension - Copy 10×, move 406× faster than Windows Explorer

by•
Copying thousands of small files mixed with large ones in Windows Explorer can take days — with no guarantee of finishing. One locked file stalls everything, errors tell you nothing, and you never know what actually made it through. RoboExtension fixes this with the same Ctrl+C, Ctrl+V, right-click — no workflow change. Only up to 10× faster small-file copies, same-volume moves 406× faster, drive-type detection, locked file handling, retry as Administrator, and a post-operation failure report.

Hey PH! 👋 I'm the solo developer behind RoboExtension.

The problem that broke me: copying a folder with thousands of small files mixed with large ones in Windows Explorer. Jobs that take days — with no assurance they'll finish. One locked file stalls everything. A vague error appears. You don't know how far it got, what actually made it through, or whether starting over will even help. So you babysit it, retry it, and lose days you won't get back.

I benchmarked every alternative I could find — TeraCopy, FastCopy integrate with Explorer like RoboExtension does, and Robocopy covers the CLI side. The integrations work, but on mixed small-and-large file workloads the gains weren't what I needed. And none of them handle locked files the way I wanted — identify the locking process, let me retry or skip, and keep going.

So I built RoboExtension. It integrates with your existing Explorer shortcuts so nothing changes about how you work. The performance numbers surprised even me during development — small-file copies run up to 10× faster than Explorer, and same-volume moves are up to 406× faster. The move gains in particular don't scale with file count or size, which is why the number looks absurd but is real.

Happy to answer any questions about how it works, what it doesn't handle yet, or the benchmarking methodology. What file operation frustrates you most on Windows?

@ghiffaryr The silent file drop issue is a nightmare scenario that probably affects way more people than realize it. Your approach of building into existing Explorer shortcuts makes a lot of sense — adoption friction is usually what kills productivity tools. Curious if you've had users test this in enterprise environments where file integrity auditing is critical, or if that's still on the roadmap.
