Copy files 10× faster than Windows Explorer — directly from the right-click menu, with real-time progress, automatic retry, and SSD-optimized multi-threading.
No credit card required.
Features
RoboExtension replaces the built-in copy, move, and delete operations in Windows Explorer with optimised equivalents. No change to your workflow is required.
Ctrl+C, Ctrl+X, Ctrl+V, Delete and Shift+Delete are intercepted in Windows Explorer. Copy and move operations use an adaptive engine that automatically selects the optimal transfer path for each scenario. Delete operations bypass Explorer's per-file shell-notification overhead.
Displays current transfer speed, estimated time remaining, file count, and the name of the file currently being processed.
Automatically selects the optimal transfer strategy and thread count for the detected hardware configuration, ensuring maximum throughput in every scenario.
Configurable retry count and wait interval. Handles locked files, dropped network connections, and busy network shares without user intervention.
When a file or folder already exists at the destination, a dialog prompts to Replace, Keep Both, Skip, or Cancel. An "apply to all" checkbox resolves remaining conflicts in one action.
When a file fails mid-operation, a dialog offers Retry, Skip, Skip All, or Abort. Windows Restart Manager identifies every process locking the file, so you know exactly what to close before retrying.
After an operation completes, all failed files are listed with their error reasons. When any failure is access-related, a one-click Retry as Administrator option re-runs the failed paths with UAC elevation.
Quick Cut, Quick Copy, Quick Paste, and Quick Delete are added directly to the Windows Explorer right-click menu. Copy and move use an adaptive engine that automatically selects the optimal transfer path. Delete enumerates the file tree in bulk before processing, avoiding Explorer's per-file shell-notification delay.
Delete moves items to the Recycle Bin. Shift+Delete removes items permanently. Both modes skip the "Discovering items" enumeration delay present in Windows Explorer by scanning the file tree up front.
Runs as a background process accessible from the system tray. No taskbar entry. Progress dialogs appear only during active operations.
How it works
RoboExtension installs once and operates transparently inside Windows Explorer. No configuration is required for standard use.
The setup wizard registers the right-click context menu entries and optionally configures RoboExtension to start with Windows.
Keyboard shortcuts and right-click menu entries work exactly as before. RoboExtension intercepts the operations and routes copies and moves through an adaptive engine combining robocopy and direct Windows file APIs.
A progress dialog displays speed, ETA, file count, and conflict prompts during active operations. It closes automatically on completion.
Interface
RoboExtension uses standard Windows dialog controls. All windows follow Windows 11 visual conventions.

Performance
RoboExtension uses its own highly optimized I/O pipeline built on top of Windows native APIs. All numbers are real, measured results — reproducible with the benchmark script in the repository.
91 MB/s — optimized I/O pipeline keeps your NVMe drive fully utilized.
552 MB/s — intelligent buffering avoids OS bottlenecks on large file transfers.
210 MB/s — adapts automatically to any mix of file sizes in the same batch.
Disk-aware scheduling eliminates the seek overhead that slows traditional file copy.
Intelligent buffering minimizes mechanical head movement for maximum throughput.
5.2 MB/s — automatically detects spinning disks and optimizes accordingly.
Purpose-built parallel delete engine — leaves every other tool in the dust.
Large file deletion on NVMe is near-instant — parallel engine keeps the drive saturated.
Scales with file count — the more files, the bigger the advantage over single-threaded delete.
Parallel delete engine bypasses the per-file shell notification overhead that makes spinning disks slow.
Parallel delete engine eliminates seek overhead even for large files on spinning disks.
Worker-thread parallel delete on mixed workloads — the more files, the bigger the advantage.
Measured on i9-13900H, NVMe PCIe 4.0 SSD, 7200 RPM HDD. Results are reproducible with the included benchmark scripts. Individual results vary by hardware and workload.
