How to Fix Cannot Access File Corrupted Error on Windows 11: Step-by-Step Solutions

Sometimes, you may try to open a file on Windows 11 and get an error saying the file is corrupted. This means Windows cannot read the file properly. It can happen with documents, pictures, videos, or other types of files.

File corruption can occur due to various reasons like sudden power loss, improper shutdowns, or problems with the storage device. Fortunately, there are simple ways to fix or recover corrupted files on your PC.

In this guide, we will walk you through easy and effective steps to handle the “Cannot Access File Corrupted” error. Each method is explained clearly, so even beginners can follow along.

By the end, you will know how to try different fixes and when to seek more advanced help.

Quick Note Before You Start

Before trying any fixes, make sure to check a few things:

Backup your files: If possible, copy the corrupted file to another location or external drive. This prevents further damage during repair attempts.
Check your storage device: Ensure your hard drive, USB stick, or memory card is properly connected and recognized by Windows.
Run a virus scan: Sometimes malware can cause file corruption, so scan your system with trusted antivirus software.
Close other programs: Make sure no other applications are using the file you want to fix.

Step 1: Use Windows File Checker Tool (SFC)

Windows has a built-in tool called System File Checker (SFC) that scans and repairs corrupted system files. Sometimes, file access errors can be fixed by repairing system components.

Here’s how to run it:

Press Windows + S and type cmd.
Right-click on Command Prompt and select Run as administrator.
In the command window, type sfc /scannow and press Enter.
Wait for the scan to complete. It may take some time.
If issues are found, Windows will attempt to fix them automatically.
Restart your computer and try accessing the file again.

This step is important because system file problems can sometimes affect how Windows reads or handles your files.

Step 2: Check and Repair the Drive Using CHKDSK

If the file is on a hard drive or USB drive, the storage itself might have errors causing the corruption. Windows offers a tool called CHKDSK to scan and repair disk errors.

Follow these steps:

Open File Explorer and note the drive letter where the corrupted file is stored.
Press Windows + S and type cmd.
Right-click Command Prompt and choose Run as administrator.
Type the command chkdsk X: /f /r /x and press Enter. Replace X: with your drive letter.
You might see a message asking to schedule the scan if the drive is in use; type Y and press Enter.
Restart your PC to let CHKDSK run and repair the drive.

This tool scans for bad sectors and fixes file system errors, which can help recover corrupted files or make them accessible again.

Step 3: Use the Windows File Recovery Tool

Windows 11 includes a free File Recovery app that can help recover deleted or corrupted files. It’s a command-line tool but very useful in tough cases.

To use it:

Go to the Microsoft Store and install Windows File Recovery.
Open Command Prompt as administrator.
Use the syntax: winfr source-drive: destination-folder /switches
For example, to recover files from drive C: to folder D:Recovery, use:
winfr C: D:Recovery /regular
Follow the on-screen instructions carefully.

This tool is helpful when other methods fail, especially for recovering lost or corrupted files.

Step 4: Try Opening the File in Another Program

Sometimes the file itself is not corrupted, but the program you are using cannot open it. Try these simple ideas:

Open the file with a different app (for example, open a Word document in LibreOffice).
Try to import the file instead of opening it directly.
Use online file repair services available for specific file types, like documents or photos.

Trying different programs can help because some apps handle file errors better than others.

Step 5: Restore Previous Versions of the File

If you have File History or System Restore enabled, you may be able to recover an older, uncorrupted version of the file.

To check this:

Right-click the corrupted file.
Select Properties.
Go to the Previous Versions tab.
If versions are listed, select one and click Restore.

This method is effective because Windows may have automatically saved backup copies you can revert to.

Alternative Advanced Method: Use Third-Party File Repair Tools

If built-in Windows tools don’t work, there are many third-party software options designed to repair corrupted files. Examples include Stellar Repair, EaseUS Data Recovery, or Disk Drill.

Keep in mind:

Choose reputable tools with good reviews.
Some tools may require purchase for full features.
Always back up your corrupted files before testing these tools.

FAQs

Why do files get corrupted on Windows 11?

Files can get corrupted due to sudden power failures, virus infections, improper shutdowns, bad sectors on the hard drive, or software bugs.
