Can't delete mp4 file

Haven't been able to delete a large mp4 file (7GB). I went to Properties>Security and changed file Permissions to System and still could not delete it.
I booted in Safe Mode and still could not delete file.
I tried playing the file in V1C Player and could not. V1C message said to look at the Log for information (don't know how to do that).
I can play and delete all other mp4 files on my PC.
Using Windows 10 up to date.

     Method 1: Use command prompt to force deletion

    cmd
    del /f /q “full file path.mp4”
    or

    cmd
    rd /s /q “Path to folder containing file”
    Method 2: Unhook the file

    1. Download and run LockHunter.

    2. Right click on the locked MP4 file and select “Unlock It”.

    3. Check “Delete It” and execute it.

    Method 3: Check for disk errors

    chkdsk C: /f
    chkdsk C: /f /r
    (You need to reboot and run the scan)

     Method 4: Reset file permissions

    powershell
    icacls “file full path.mp4” /reset /T /C /L
