File copy, move and delete for Windows, powered by robocopy. Real-time progress, automatic retry, and multi-threaded transfers built into Explorer.
No credit card required.
Features
RoboExtension replaces the built-in copy, move, and delete operations in Windows Explorer with robocopy-backed 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 run through robocopy. 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.
Detects whether the source and destination drives are SSD or HDD and selects the appropriate robocopy thread count accordingly.
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 robocopy. 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 them through robocopy.
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
robocopy is a Microsoft-built tool included in every edition of Windows since Vista. Its multi-threaded mode (/MT) is not accessible from Windows Explorer. RoboExtension exposes it through standard keyboard shortcuts and the right-click menu.
robocopy /MT:8 multi-threading — widely reported 30–80% gain on SSD for many small files (SuperUser, r/sysadmin).
robocopy /MT:8 keeps the network pipe saturated by issuing parallel reads. 2–5× gains on LAN are widely reported (SuperUser, Microsoft Docs).
Figures represent typical ranges from community benchmarks (SuperUser, r/sysadmin, Microsoft TechNet). Individual results vary by hardware and workload. robocopy is a built-in Windows tool — available since Windows Vista.
