Question Can't delete mp4 file

[cool09]

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 VLC Player and could not. VLC 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.

Browse to it in 7-Zip and delete it in there, or use that to rename it to something Windows can delete.

If you have to resort to a live boot of Linux to delete something in NTFS, best to do a chkdsk afterwards once back in Windows.

I have WINRAR installed.
Is there anything else I can do in "Properties" to try and delete it?
The file is on an external HDD. The HDD has been working well with no problems. Should I run chkdsk on the HDD?
I don't know why it won't even play in VLC Player. It played fine last week then I split it in avidemux and now unable to delete it.

As a last resort, boot a usb with a linux distro and use its file manager to delete it.

You could always try it the same way as with 7-Zip: but if WinRAR can't delete or rename it directly, try a right-click and Add files to archive with Delete files after archiving checked (under the Archiving options in the General tab). The undeletable file may be deleted, and the new compressed folder should be deletable. The only problem is at 7GB this method may take a long time
