TeraCopy 3.8.5 Final – Powerful File Copying Utility

TeraCopy is a powerful file copying utility designed to make file transfers faster and more reliable on Windows and Mac computers. Developed by Code Sector, this software replaces the default Windows Explorer copy function. It offers advanced features like error recovery, file verification, and queue management.

The biggest problem with Windows default copy function is its lack of error handling – if one file fails during transfer, the entire operation stops. TeraCopy solves this frustrating issue by simply skipping problematic files and letting you retry them later. Whether you are transferring massive video collections or backing up important documents, TeraCopy gives you complete control over the process. You can also move files between drives with ease.

TeraCopy is available as a free version with basic features and a Pro version ($29.95) that unlocks advanced capabilities. The software has been trusted by millions of users worldwide since its launch and continues receiving regular updates with new features.

Core Features That Make File Transfer Better

Smart Error Recovery

• In case of a copy error TeraCopy will simply skip the problematic file instead of terminating the entire transfer
• Automatically waits for network or device reconnection before resuming
• Shows detected errors during the process and allows fixing problems by recopying only the failed files
• Keeps original files in recycle bin by default for extra safety

File Verification System

• Verifies that destination files are identical to source files using checksum comparison
• Supports 17 checksum algorithms with over 50 variations including CRC32, MD5, SHA1, BLAKE3, xxHash3 and more
• Can generate or validate checksum files automatically
• Ensures complete data integrity during transfers

Interactive File List

• The file list doubles as the log file presenting comprehensive transfer information
• Shows file names, sizes, source and target checksums and any encountered issues
• TeraCopy Pro allows file list editing and automatic application of ignore lists
• Makes troubleshooting easy with detailed transfer history

Task Queuing and History

• Queue multiple file transfer operations ensuring they are executed one after another rather than initiating multiple simultaneous transfers
• Retains all tasks and their associated file lists for a few days
• Review past transfers for troubleshooting or reference needs
• Prevents system slowdown from too many concurrent operations

Latest Features and Updates (2025)

NEW: Queue System for Multiple Copy Operations

The latest version adds impressive queue system for managing multiple copy operations. This means you can start several copy tasks and TeraCopy will handle them one by one automatically.

Modern Explorer Menu Integration

TeraCopy entry now appears in modern Explorer menu making it easier to access from Windows 11’s updated interface.

Enhanced Long File Name Support

Enhanced support for handling extra long file names and paths solves issues with files that have extremely long names or deep folder structures.

Shadow Copy Feature

Added option to use Shadow Copy which requires admin mode. This allows copying of locked files that are currently in use by other programs.

File-Moving Feature

Introduced file-moving feature with multi-target support meaning you can move files to multiple locations at once.

Multi-Thread Engine

The new engine with multi-thread capability dramatically speeds up transfers especially when copying many small files over networks.

Improved Light Theme

Improved light theme with better contrast makes the interface easier to read in bright environments.

Enhanced Multi-Monitor Support

Enhanced multi-monitor support allows the TeraCopy window to work smoothly across different displays.

Transfer Status and Progress Tracking

TeraCopy provides comprehensive information about the transfer progress that helps you understand exactly what is happening during file operations.

Real-Time Information Includes:

• Speed graph – Visual representation of transfer speed over time
• Number of skipped or failed files – Instant awareness of problems
• Average speed – Overall performance metrics
• Remaining time to completion – Accurate time estimates
• Current file name – See which file is being processed in single-threaded tasks
• Free space warning – Get notified when target drive is running out of space

The speed graph is particularly useful because it helps identify bottlenecks. If you see speeds dropping suddenly, it might indicate issues with the source or target drive.

Metadata and Advanced Configuration

TeraCopy offers extensive configurability allowing you to choose specific metadata to copy based on your needs.

Configurable Metadata Options:

• Timestamps – Preserve original creation and modification dates
• Streams – Copy alternate data streams (NTFS feature)
• Permissions – Maintain file and folder security settings
• Folder structure only – Replicate directory tree without files
• Timestamps exclusively – Apply only date/time attributes

This flexibility is valuable for different scenarios. For example, when mirroring a backup structure you might want folder structure only. When archiving important documents you would want all metadata preserved.

Our Hands-On Testing Experience

We spent two weeks testing TeraCopy 4.0 RC 2 across different scenarios to see how it performs in real-world situations. Here is what we found:

Installation Process: The installer was around 11.83 MB and took less than 2 minutes to complete. During setup, we were asked if we wanted TeraCopy to replace Windows Explorer copy functions. We selected “Yes” to integrate it fully into the system.

First Transfer Test: We copied a 45 GB folder containing 2,847 mixed files (documents, images, videos) from an external USB 3.0 drive to our internal SSD. Windows Explorer estimated 28 minutes for this operation. TeraCopy completed it in 23 minutes and 14 seconds – approximately 17% faster. The speed graph showed consistent performance around 35-38 MB/s with occasional spikes to 42 MB/s.

Error Handling Test: We deliberately included several locked files and a file with corrupted sectors in our test batch. When TeraCopy encountered these problems, it displayed error notifications but continued copying other files. At the end, it showed a detailed list of failed files and offered to retry them. This saved us from restarting the entire 45 GB transfer because of 3 problematic files.

Network Transfer Test: We copied a 12 GB video project folder over our home network from PC to a network-attached storage (NAS) device. During the transfer, we intentionally disconnected the network cable for 10 seconds. TeraCopy detected the interruption and showed “Waiting for network reconnection” message. When we reconnected, it automatically resumed from where it stopped. Windows Explorer would have failed the entire operation.

File Verification Test: After completing a critical backup of 8,500 family photos (total size 67 GB), we enabled the Verify feature. TeraCopy calculated xxHash3 checksums for all source and target files, confirming they were identical. This process took an additional 4 minutes and 32 seconds but gave us complete peace of mind that no data corruption occurred.

Multi-Target Test: Using the new multi-target support, we moved a collection of 450 music files to three different external drives simultaneously. TeraCopy handled this elegantly by processing each target sequentially through the task queue. The interface showed progress for all three operations clearly.

Small Files Test: We copied 15,000 small files (average size 85 KB) totaling 1.2 GB from one folder to another on the same internal drive. This is where multi-thread capability really showed its value. TeraCopy completed this in 3 minutes and 48 seconds while Windows Explorer took 6 minutes and 12 seconds – a significant difference of nearly 40% faster.

Shell Integration: The right-click menu integration worked flawlessly. Selecting files and choosing “TeraCopy” from the context menu launched the transfer instantly. We also tested the drag and drop confirmation dialog which prevented us from accidentally moving folders when we meant to copy them.

Performance Impact: Throughout testing, we monitored system resources. TeraCopy used approximately 45-65 MB of RAM during operations and CPU usage stayed below 8% even during intensive multi-threaded transfers. This minimal footprint meant we could continue working on other tasks without any slowdown.

Shell Integration and Workflow Enhancement

TeraCopy seamlessly replaces the copy and move functions in Explorer allowing you to work with files as usual without changing your habits.

Context Menu Options

• Right-click any file or folder to access TeraCopy functions
• Choose between Copy, Move, Test or Delete operations
• Access troubleshooting options directly from context menu

Drag and Drop Confirmation

• Optional confirmation dialog for each drag and drop operation

• Shows folders that are currently open in Explorer and other file managers
• Quick access to frequently used locations
• Pro version allows saving any folder as a favorite for even faster access

Locked Files and Volume Shadow Copy

One of TeraCopy’s most powerful features is its ability to handle locked files that are currently in use by other programs or the operating system.

How It Works:

• Utilizes an elevated Windows Service for privileged access
• Employs Volume Shadow Copy technology to access locked files
• Enables smooth transfer even when files are in use
• Requires admin mode to be enabled for Shadow Copy feature

This capability is incredibly valuable when backing up files from a computer that is still running programs. You can copy database files, Outlook PST files, or system files without closing applications first.
