What is Windows Attachment Manager?

Under Microsoft® Windows® XP SP2 and Windows Vista® any file obtained via an e-mail attachment in Microsoft Outlook® Express or Windows Mail, or an internet download via Internet Explorer®, and saved to an NTFS drive, will now have a 'Zone.Identifier' assigned to the file. The Windows operating system may, based on the file's Zone.Identifier, restrict your ability to open certain files. The level of restriction is based on several factors including the file's type, the type of data it contains, it's associated application and the Web Zone identified by the Zone.Identifier. Mail attachments have higher restrictions than files downloaded from the Internet, and some files types (mostly executable and script-type files) are considered to be a higher risk than others.
