Encountering Windows Error Code ERROR_177 can be frustrating, especially if you don’t know where to start. This error typically means “The system cannot move the file to a different disk drive”, which often arises when trying to manipulate files across drives or dealing with permission or disk issues.
Don’t worry! We’ve created this detailed, step-by-step guide to help you understand and resolve ERROR_177 in Windows efficiently and safely. Let’s dive in.
What is Windows Error Code ERROR_177?
Before diving into fixes, it’s helpful to understand what ERROR_177 means. This error occurs when Windows fails to move or transfer a file from one drive to another — often due to permission restrictions, file locks, or disk-related problems.
Knowing this can help you better identify the cause and choose the right fix.
Step 1: Identify When and Where the Error Occurs
Start by pinpointing the exact action that triggers the ERROR_177. Common scenarios include:
- Trying to move files between drives (e.g., from C: to D:)
- Using certain apps or scripts that copy or move files
- Modifying files on external storage devices
Tip: Note the exact file(s) and the drives involved to make troubleshooting easier.
Step 2: Check Disk Space on Target Drive
One straightforward reason for this error is lack of disk space on the target drive.
- Open File Explorer
- Right-click the target drive (where you want to move the file)
- Select Properties
- Check Free space
If the drive is nearly full, free up space by deleting unnecessary files or transferring them to another drive.
Step 3: Verify File and Folder Permissions
Often, ERROR_177 appears because the system or current user doesn’t have sufficient permissions to move the file.
How to Check and Modify Permissions:
- Right-click the file or folder you want to move.
- Select Properties.
- Go to the Security tab.
- Check the permissions for your user or group.
- If needed, click Edit to modify permissions and ensure you have Full Control.
- Apply changes and try moving the file again.
Step 4: Use Administrator Privileges
Some operations require elevated permissions.
- Right-click the program or File Explorer and select Run as administrator.
- Try moving the file again.
Running as Administrator can bypass some permission restrictions causing ERROR_177.
Step 5: Check if the File is Open or Locked
Windows may prevent moving files that are currently open or used by another application.
- Close all programs that might be using the file.
- If unsure, restart your computer to clear locks.
- Alternatively, use a tool like Process Explorer to identify which process is using the file.
Step 6: Run CHKDSK to Fix Disk Errors
Corrupted file systems can cause file movement errors.
- Open Command Prompt as administrator:
- Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
-
Type the following command and press Enter:
chkdsk /f /r X:
Replace X: with your drive letter where the file resides or where you want to move it.
- Follow the prompts, restart if needed.
CHKDSK will scan the drive for errors and repair them, which may resolve ERROR_177.
Step 7: Try Moving the File via Command Prompt
Sometimes, GUI-based moves fail but command-line moves succeed.
- Open Command Prompt (Run as administrator).
-
Use the
movecommand:move "source_path\filename.ext" "destination_path\"
Example:
move "C:\Users\JohnDoe\Documents\file.txt" "D:\Backup\"
If this command works, it can isolate whether the problem lies with the graphical interface or something deeper.
Step 8: Disable Antivirus Temporarily
Antivirus programs can occasionally block file operations they erroneously flag.
- Temporarily disable your antivirus or real-time protection.
- Attempt to move the file again.
- Don’t forget to re-enable antivirus right after.
Step 9: Update Windows and Drivers
Ensure your system is up-to-date, as bugs and issues causing ERROR_177 may have patches from Microsoft.
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates.
- Install all available updates.
- Also, update drivers for your storage devices via Device Manager.
Step 10: Use Third-Party Tools for File Management
If the error persists, tools like TeraCopy or Unlocker might help move locked or stubborn files safely.
- TeraCopy enhances stability and error handling during file transfers.
- Unlocker can unlock files used by other programs.
Download these tools from official websites and follow their instructions.
Summary
Windows Error Code ERROR_177 often involves permission issues, file locks, or disk problems when moving files between drives. By following these steps — checking permissions, running CHKDSK, using admin rights, and trying command-line moves — you can resolve the error and get your files moving smoothly again.
