Part 1: What Is Unspecified Error Copying File or Folder?

Essentially, this generic error message means some condition on your computer is preventing the file or folder transfer from completing properly. The file or folder itself may show additional symptoms - it might fail to open, have a lock icon on it, or be hidden from view.

Other times, additional error messages may be displayed along with the unspecified error, such as "Access denied", "Parameter incorrect", or "Catastrophic failure" - unfortunately, none of these provide much clarity on the exact cause.

Some potential causes for running into this error include:

  • The destination drive is corrupted or write-protected
  • Trying to copy large files over 4GB to a FAT32 partition
  • The file/folder is encrypted, locked or restricted
  • Not enough free space on the target destination drive

So in summary, the unspecified error copying message is Windows' vague way of telling you there is a problem related to that particular file or folder you are attempting to copy. Once aware of the likely culprits, you can better troubleshoot and resolve this issue.

Part 3: How to Fix Error Copying File or Folder?

If you have faced the frustrating “Error Copying File or Folder – Unspecified error” message in Windows, there are several tweaks you can try to resolve this issue. After diagnosing the likely causes, apply the appropriate solution to finally copy your important files successfully again.

Let’s look at 6 proven troubleshooting methods to fix the unspecified error while copying data:

Method 1: Format the Target Drive to a Compatible File System

If you get the error when trying to copy large files over 4GB to drives formatted with the FAT32 file system, this incompatible file system is often the culprit. FAT32 has a max file size limit of 4GB even though the overall drive capacity can be higher.

To permit transferring of huge files beyond 4GB, consider reformatting the target drive to a more modern file system like NTFS or exFAT instead.

Both these file systems overcome FAT32’s single file size restriction. Just ensure you backup existing data on the drive first before reformatting to prevent content loss.

The steps are:

  • Right-click on target drive in File Explorer > Select Format
  • Choose NTFS/exFAT file system
  • Click Start and confirm reformatting

This updates the file system allowing you to now copy those large video clips, disc images, and other big files without size constraints.

Method 2: Extend the Target Partition

If your target drive partition has insufficient free space, trying to copy large files to it can trigger the unspecified error. A handy all-in-one tool like 4DDiG Partition Manager allows easily expanding the problematic partition to resolve such space constraints.

4DDiG Partition Manager is a user-friendly disk management utility for Windows that offers powerful partitioning capabilities.

To increase partition space on your target drive showing the copy error:

  • Launch 4DDiG Partition Manager and select the partition
  • Right click on it and choose 'Resize/Move Partition' option
  • Use its slider or input exact size to expand the partition
  • Click Align Partition and then Apply changes

So in a few simple steps, you can rapidly extend partitions using this tool and overcome file copy issues due to space limitations.

Method 3: Remove Write-Protection on Target Drive

If your target drive has a 'read-only' attribute enabled, you may encounter the error when attempting to copy files to it. This write-protection restricts making any changes to the drive.

To enable write access, the read-only attribute needs to be cleared. This can be done using the command-line diskpart tool:

  • Open elevated Command Prompt
  • Type diskpart and press Enter
  • Next type list volume to view volumes
  • Select the write-protected drive with select volume X (X is drive number)
  • Issue command attributes disk clear readonly

    remove write protection

This should remove the disk's read-only tag allowing you to now copy over files without write access issues. The drive permissions are reset back to the default writable state. Verify by trying to paste some test files onto this volume after running above commands.

However, if the read-only attribute persists, you may have to check your hard disk health. The unspecified error in such cases could indicate impending drive failures.

Method 4: Decrypt the Files or Format the Disk

Encrypted or password-protected files appear normal but copying them results in errors due to altered internal contents. Use the encryption software to first decrypt files before transfer.

Similarly, inspect your target drive for file system corruption using CHKDSK, which may also block writes. Backup data and reformat corrupted volumes to restore functionality. Lastly, check physical components like cables, connectors for flaws if drive errors persist.

Method 5: Change the User Account

As a regular limited Windows user, you may lack permissions to access protected files and folders leading to copy errors. Sign out and login to an administrator account having full access rights.

Then try recopying the restricted files that failed earlier. If successful, insufficient permissions in your normal user profile is likely the culprit.

Now either keep using a privileged account for those copy needs or enable enhanced sharing settings in limited profiles.

Method 6: Modify File/Folder Permissions

If certain files or folders show a lock symbol or have restricted access, copying them even on an admin account may fail with permissions errors. Every file/folder has user access rules defining operations allowed.

To enable transfer of protected files, change the permission settings as below:

  • Right-click protected file/folder, open Properties
  • Go to Security tab > Advanced
  • Select user account entry and click Edit
  • Allow 'Write' permissions under Access Control Settings
  • Click OK and reattempt copy of files

    folder permissions

You can also take ownership if you are the file owner. Ownership grants you full control over changing permissions.

Modifying file and folder authorization rules accordingly can help lift previous restrictions. Now when you try to copy data from these locations, the transfers should proceed successfully without a vague unspecified error.
