Warning can't create file, even when filter says to skip it

[glennman]

Windows 11, running as Administrator, mirror sync.
I keep getting this kind of error for a few files, all with the ffs_tmp suffix.

8:49:24 PM Warning: Cannot write modification time of
"D:\lenovo-c-data\ProgramData\Lenovo\Udc\Broker\SharedUser\D7AAB420-8339-43EA-821A-FD56632F096A_notify-e91f.ffs_tmp".
ERROR_CANT_ACCESS_FILE: The file cannot be accessed by the system. [CreateFile]

I have this in the Exclude filter
*.ffs_tmp

Any idea why it does it not skip these files?

You can't exclude .ffs_tmp files, they are hard-coded to be included since they are a part of how FFS works.
You need to exclude the file with the actual extension it has:
'D7AAB420-8339-43EA-821A-FD56632F096A_notify.XXXX'
"XXXX" needs to be the extension of the actual file
