How to Fix “The Parameter is Incorrect” File Error in Windows 11: Step-by-Step Solutions

Encountering the “The parameter is incorrect” error in Windows 11 can be frustrating. This error often appears when trying to access, copy, or move files and usually indicates a problem with the file system or hardware settings.

Fortunately, there are several straightforward solutions to fix this problem. Most methods do not require advanced computer skills and can be done step-by-step.

In this article, you will find easy-to-follow instructions to resolve the error and get your files back to normal.

Let’s start by understanding what you should check before diving into fixes.

Quick Note: Important Checks Before You Begin

  • Check the Drive Connection: If you are using an external drive or USB, make sure it is properly connected. Sometimes loose cables cause this error.
  • Restart Your Computer: A simple reboot can clear temporary glitches that may trigger the error.
  • Verify File Names: Files with very long names or special characters sometimes cause issues. Try renaming the file to something simple.
  • Backup Important Data: Before performing disk checks or repairs, back up your important files to avoid data loss.

Step 1: Run the Windows Error Checking Tool

This tool scans your drive for errors and attempts to fix them automatically. It is a simple first step to solve parameter errors caused by file system problems.

  1. Open File Explorer by pressing Windows + E.
  2. Locate the drive where you see the error (for example, C: or an external drive).
  3. Right-click the drive and select Properties.
  4. Go to the Tools tab.
  5. Under Error checking, click Check.
  6. Windows will scan the drive. If errors are found, it will offer to fix them. Follow the prompts to repair.

Why this helps: The error checking tool fixes file system inconsistencies that often cause “The parameter is incorrect” error.

Step 2: Use the Command Prompt to Repair the Drive

If the basic error checking didn’t work, using the command prompt with the CHKDSK tool is the next step. It performs a more thorough scan and repair.

  1. Press Windows + S, type cmd, then right-click Command Prompt and choose Run as administrator.
  2. In the Command Prompt window, type the following command and press Enter:
chkdsk X: /f /r /x

Replace X: with the letter of the drive giving the error.

  • /f fixes errors on the disk.
  • /r locates bad sectors and recovers readable information.
  • /x forces the drive to dismount before the process starts.

Wait for the scan and repair to complete. This may take some time depending on the drive size and condition.

Why this helps: CHKDSK repairs deeper file system issues and bad sectors which often cause parameter errors.

Step 3: Format the Problematic Drive (Use with Caution)

If the error continues and you don’t have critical data on the drive, formatting it can resolve file system corruption completely. This deletes all data on the drive, so make sure to back up first.

  1. Open File Explorer.
  2. Right-click the affected drive and select Format.
  3. Choose the file system type (usually NTFS for Windows).
  4. Uncheck Quick Format for a thorough format, or leave it checked for a faster format.
  5. Click Start to begin the format process.

Why this helps: Formatting resets the file system and removes any corruption causing the error.

Step 4: Update or Reinstall Device Drivers

Sometimes faulty or outdated device drivers for your storage device can cause this error. Updating or reinstalling drivers can fix communication problems between Windows and the hardware.

  1. Press Windows + X and select Device Manager.
  2. Expand the Disk drives section.
  3. Right-click your drive and select Update driver.
  4. Choose Search automatically for drivers.
  5. If Windows doesn’t find anything, you can also try uninstalling the driver (right-click > Uninstall device) and then restart your PC. Windows will reinstall the driver automatically.

Why this helps: Updated drivers ensure proper communication and may resolve errors caused by driver problems.

Step 5: Use System File Checker (SFC) and DISM Tools

Corrupted system files can sometimes cause errors related to file handling. Running SFC and DISM commands can repair these files.

  1. Open Command Prompt as administrator (see Step 2).
  2. Type the following command and press Enter:
sfc /scannow

This process scans all protected system files and replaces corrupted ones.

After SFC finishes, run the DISM command to fix the Windows image:

DISM /Online /Cleanup-Image /RestoreHealth

Wait for the process to complete, then restart your computer.

Why this helps: Fixing corrupted system files can clear errors affecting file operations.

Alternative Methods and Advanced Options

  • Try Safe Mode: Booting Windows in Safe Mode can help identify if third-party software causes the error.
  • Check for Windows Updates: Sometimes Microsoft releases fixes for such errors in updates.
  • Use Third-Party Disk Repair Tools: Tools like MiniTool Partition Wizard or EaseUS Partition Master offer advanced repair options.
