(The long number is a security identifier number). I believe you can remove it via the security tab in the properties (Right click on the file and select properties, click security). If is sharing the file/folder with the "unknown contact," I think you can also remove that account in the sharing tab. I don't have my Windows 7 machine up and running so I shooting in the dark here but hope that helps. :wave:
