  2. Hard disk errors or bad sectors.
  3. The file or directory is corrupted and unreadable.
  4. Virus or malware infection.

Fortunately, there are corresponding solutions to fix the above issues, and we will show you the detailed fixes in the next part.

However, in most cases, you don’t know what the exact reason of the file cannot be accessed by the system error is. Thus, you can try the following solutions one by one to get rid of the error code 0x80070780.

Solutions to the File Cannot Be Accessed by the System Error Solution 1: Use the System File Checker to Fix Corrupted or Damaged System Files

One of the top reasons for the file cannot be accessed by the system error is the corrupted or damaged system files. In this situation, you can use the System File Checker to fix them.

Step 1: To run the System File Checker tool (SFC.exe), you need to enter Command Prompt firstly.

If you are running Windows 8/8.1:

Please point to the lower-right corner of the screen, and then click on the Search option where you need to input Command Prompt. From the search result, you need to right-click on Command Prompt and then choose Run as administrator. Then, you may need to input the administrator password or receive a confirmation, just input the password or click on Allow to continue.

If you are running Windows 10/7/ Vista:

Please click on Start and then type Command Prompt or cmd into the Search box. Then, right-click on the Command Prompt option and choose Run as administrator. When you are prompted for an administrator password or a confirmation, just type the password or click on the Yes button.

Step 2: If you are using Windows 10/8.1/8, please firstly run the inbox Deployment Image Servicing and Management (DISM) tool before running the System File Checker.

To use the DISM tool, you need to type the following command and press the Enter button:

DISM.exe /Online /Cleanup-image /Restorehealth

Step 3: Type sfc /scannow command into the Command Prompt and press the Enter button.

Then, the sfc /scannow command will begin to scan all the protected system files and replace the corrupted files with a cached copy which is located in a compressed folder at %WinDir%\System32\dllcache. Here, %WinDir% represents the Windows operating system folder like C:\Windows.

It will take a while to finish the scan process. Please be patient.

Step 4: When the verification ends, you will see the scan result:

1. Windows Resource Protection did not find any integrity violations.

It means that there are no damaged or corrupted system files.

2. Windows Resource Protection could not perform the requested operation.

To deal with this issue, you need to use System File Checker scan in safe mode to guarantee that the PendingDeletes and PendingRenames folders are there under %WinDir%\WinSxS\Temp.

3. Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.

This means that the corrupted system files have already been fixed, and you can go to check whether the file cannot be accessed by the system error still exists.

4. Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.

When you see this message, you need to manually replace the corrupted sys… copy of the file.

Solution 2: Check and Repair Bad Sectors & Disk Errors

If solution 1 doesn’t work for you, this means that the damaged or corrupted system files are not the exact reason for Error 0x80070780: The file cannot be accessed by the system issue.

Now, you need to consider if there are bad sectors or disk errors on the drive. If yes, you need to take some measure to shield the bad sectors or fix the errors on the drive.

The best choice is to use CHKDSK to check and fix the issue. Suppose that drive G: encounters error code 0x80070780.

Step 1: Still, you need to enter Command Prompt. The access way is mentioned in solution 1 and we will not repeat it here.

Step 2: Please type chkdsk g: /f /r in the Command Prompt window and then tap the Enter key. Here, g stands for the target drive letter. Of course, you need to replace it with your own one.

You can close this window when the checking and fixing process ends. After, you should go to check whether the file cannot be accessed by the system issue still exists.

Solution 3: Use Anti-virus Software

The infected viruses or malware can also cause Windows error 0x80070780 issue. So, you can search for reliable anti-virus software on the internet, download and install it on your computer to kill the viruses and malware.
