Microsoft RichCopy
Microsoft RichCopy is a multi-threaded file-copying utility originally developed by Microsoft engineer John Howard. It was created to improve on the built-in Windows copy tools by providing faster, more reliable transfers—especially for large batches of files or complex directory trees.
What RichCopy Does
- Multi-threaded copying: Runs multiple copy jobs in parallel to increase throughput.
- Preserves file metadata: Keeps timestamps, attributes, and security (ACL) information where supported.
- Selective copying: Filters by file type, size, or modification date.
- Retry and error handling: Allows retries on transient errors and can skip problematic files.
- GUI and command-line options: Provides a graphical interface for ease of use and command-line parameters for scripting.
When to Use RichCopy
- Migrating large directory trees between servers or storage devices.
- Copying many small files where single-threaded tools are slow.
- Backing up data while preserving ACLs and timestamps.
- Performing repeated or scheduled bulk copies where performance matters.
Basic Usage (GUI)
- Launch RichCopy.
- Set the source and destination folders.
- Choose copy options: include/exclude filters, preserve security, and attribute handling.
- Set thread count (more threads can increase speed but use more CPU and I/O).
- Start the job and monitor progress; review any reported errors.
Basic Usage (Command Line)
RichCopy supports command-line operation, useful for scripting and scheduled tasks. A typical pattern:
- Specify source and destination paths.
- Set thread count and filters.
- Include retry and logging parameters.
(Exact command-line switches vary by RichCopy version; consult the tool’s help for precise syntax.)
Performance Tips
- Increase threads for high-bandwidth, low-latency storage (e.g., LAN, SAN).
- Reduce threads if copying over high-latency networks (e.g., WAN) to avoid congestion.
- Use file filters to skip unnecessary files and reduce I/O.
- Run during off-peak hours to maximize available network and disk resources.
Limitations and Alternatives
- RichCopy is not actively maintained by Microsoft; compatibility with the newest Windows releases may vary.
- For modern, supported alternatives consider:
- Robocopy (built into Windows) — robust, scriptable, and widely supported.
- Third-party tools like FastCopy, TeraCopy, or commercial backup solutions for advanced features and active support.
Troubleshooting Common Issues
- Permissions errors: run with administrative privileges if copying ACL-protected files.
- Incomplete copies: check logs for skipped files and rerun with retries enabled.
- Performance problems: adjust thread count and test different settings based on your environment.
Conclusion
Microsoft RichCopy remains a useful utility for speeding up large or complex file-copy tasks, thanks to its multi-threaded design and flexible options. However, because it’s no longer actively maintained, evaluate compatibility with your environment and consider modern alternatives like Robocopy or dedicated third-party tools for long-term use.
