Therefore, you can try to run a “Disc Check” scan to check the drive for bad sectors.  For that:

  1. Press the “Windows” + “R” keys simultaneously.
  2. Type in “cmd” in the dialogue box and press “Enter“.
    Typing in “cmd”
  3. Type in “chkdsk c: /f” and press “Enter” to initiate it.

Solution 6: Run as Administrator to solve steam content file locked

In some cases, steam requires special permissions to access certain folders and files. If the special permissions are not granted it may be blocked by the Windows from accessing the folder and the “Content File is Locked” message might show up. Therefore, in this step, we will be running “Steam” as Administrator. For that:

  1. Rightclick on the steam icon and select the “Properties” option.
  2. Right-clicking on the steam icon and selecting “Properties”.
  3. Click on the “Compatibility” tab and check the “Run asmistrtrator”option.
  4. Clicking on “Compatibility” and checking the “Run as Administrator” box
  5. Click on “Apply” and then on “OK“.
  6. Run Steam and check to see if the issue persists.

In some cases, the Content file locked Steam error may appear because of the antivirus on your computer. You can disable the antivirus while you update the game. This method differs depending on the antivirus you use, so be sure to look for instructions online on how to disable your antivirus.

If disabling the antivirus doesn’t help, you might have to uninstall your antivirus or switch to different antivirus software. If you’re in need of reliable antivirus software that won’t interfere with your gaming sessions, be sure to try out Bitdefender.
