Advanced Permissions Problem

I want to change the Title of a single file in it's Properties > Details Tab > Description line.
When I try to make the change by going to the "Remove Properties and Personal Information" link and Apply, I get the message: "You'll Need To Provide Administrator Permission To Apply Properties To This File", and no changes are made.

This is not a system file or software file. It is a video.

I have done all the usual steps to gain access to this file (and others exhibiting the same behavior):
I have taken Ownership of the file (My User Account). I own the folder it is in.
I have checked to be sure I have "Full Control".
I have disinherited the file and created all new settings.
I have tried changing ownership to Administrators and Everyone.
I have given Everyone full control over this file.
I have checked Effective Access and all items are checked.

In all instances the Special Permissions check box is greyed out.

What am I missing?

To check if it's a path rather than a file related problem you could try copying it to your desktop, then trying that on the copy.

Were you logged in as administrator?

Does the file sit in a shared folder? If you're accessing the file through the share, check share (not NTFS) permissions on the shared folder as well. Try full control to everyone

Yes, it's in a shared folder. And the Share Permissions are Full Control for Everyone on that Folder.

I should also mention that I tried checking the Unblock box for "This file came from another computer and might be blocked to help protect this computer".

So you actually mean it's a blocked download.... oh... had you said...
- to stop this happening for future files, it's suggested you enable this group policy:


If you have Win 10 Home, you need the equivalent registry change:
Disable Downloaded Files from being Blocked in Windows Windows 10 Security System Tutorials

Fixes for 'can't unblock' that worked for some people:
Clicking on s security properties has - Microsoft Community

This has been reported on this forum, so do try searching and see what you find.

Thanks Dalchina.
So that message will only come up on files that are actually blocked?
Because I have other files in that folder that have that message in Properties and I can edit them fine.

I'll try the zip / unzip soon.

Also, I do not get any security warnings when opening these files to play. I do get those warnings when I open executables and driver downloads.
