Strange error "SetFileSecurity"

[questionatsf]

I try to mirror some files to my NAS drive with FFS 6.11, but on each file I got the error message Errorcode 5 ... 'SetFileSecurity'.
But if I copy the files via totalcommander it works fine, same source, same dest, same user?!
I tried it with several programs, all of them are able to create, overwrite, delete files on the destination.
I double check it, I have full access to the destination, I can not figure out why only FFS is unable to write to it.
But now it becomes absolutly strange, if I delete a file in FFS via context menu it works.
I have no idea where to start the search where the error comes from.
Any ideas?

You have enabled "copy NTFS permissions".

No, disabled (btw. I tried to start FFS as administrator already)

Any ideas how to fix this? I get the exact same error.

Error Code 1 Incorrect Function (setFileSecurity) full permissions on NAS.

I am getting thesame issue, pls post if you found the solution.. Thank you... run as admin and the following error:

Cannot write permissions of "\\Nas\home\Music Videos\Jazz Chillout\Midnight Ocean (Smooth Night Mix)~8d3b.ffs_tmp".

ERROR_INVALID_FUNCTION: Incorrect function. [SetFileSecurity]

Same exact issue. Robocopy copies the permissions to the NAS just fine.

Are you running FFS "as administrator" ?

Yes
