So maybe the error comes up when your process tries to overwrite a file with such attributes in tcToFolder? If that's the case, you may look (Sergey's website or Dimitriy Moguilevets) for some API to set the attributes first to allow deletion, so your process would be able to overwrite it.

Hi Dragan,
the destination folder in this case does not have a thumbs.db there. The attributes on the file to be unzipped might be the source of the problem as they are Hidden and System.
As far as getting the last error, I don't think Craig ever got around to that part yet.
UPDATEA thumbs.db was there in the folder. I had show hidden files and folders on, but needed to set Hide protected operating system files off to see it.
