I get the following error when trying to save a specific file:

Saving file h:/some/file.txt...
file-extended-attributes: Getting ACLs: Input/output error, h:/some/file.txt

This is unexpected since both Emacs 26.3 and notepad.exe are able to
write to this file. Even though I also get an error when using the
Get-Acl command in PowerShell.
