Prevent ._ file creation on macOS, or delete them from macOS/Windows

Question

I have a network share that I access daily from both a Windows laptop and a MacBook Pro. The Pro (or rather the VLC app) keeps insisting on creating a ._<file name> file for every video that I open from this network share on the Pro.

How can I prevent these files from ever being created? I've spent 2 hours researching this before giving up, and deciding to just delete them from the Windows side instead, since I already have a batch script set up to automatically map the share to a drive letter on startup.

But this has proved to be even more difficult! I've tried Get-ChildItem -Path V:\._* -Recurse -Force | Remove-Item but this results in Remove-Item : Cannot remove item <file name>. You do not have sufficient access rights to perform this operation.

So I've tried several variations of $acl = Get-Acl <known good file>; Set-Acl -Path <file that won't f*** off> -AclObject $acl, but those commands all come back with Set-Acl : Some or all identity references could not be translated.

I'm almost at my wit's end over this! Somebody please save me from this madness!! MTIA :-)

P.S: I'll accept a solution that works from either side (Mac or Windows) but preferably it would be awesome if these files never got created in the first place. Thanks again!

UPDATE: Here's a screenshot of the folder permissions in Windows:

I set the owner explicitly just now, and tried removing the other two ACLs through that window, but no dice...they just come straight back when hitting 'Apply'! :@

I also can't add perms. from the local computer...the dialog will only allow me to choose the network address under 'Locations':

And here's the share tab as requested by @ErjenRijnders:

My router is pretty much the cheapest, most run-of-the-mill one that my ISP gives its customers for free, so I'm surprised it even supports all of this, let alone more LOL.

Answer 1

Is your network share running on a Windows File server? Than make sure that the directory where the files are created have sufficient permissions for the user that is trying to delete the files. So mstsc to the remote server, open the share locally like C:\share and check permissions. That means you need give the user SMB and NTFS permissions, not one of them because you are trying to delete it from a network share. This also counts for a Linux share, make sure it has the right NFS permissions as well.

You can also try to run the same command from an elevated command prompt.

Probably the best option is to tell the server (if it's Windows Server) to actually execute the command like this:

Invoke-Command -ComputerName Server01 -ScriptBlock { Get-ChildItem -Path V:\._* -Recurse -Force | Remove-Item }
