Consider the following scenario:
  • You download a compressed (zip) file from the Internet to a computer that is running one of the following operating systems:
    • Windows Vista
    • Windows Server 2003 Service Pack 1
    • Windows Server 2003 Service Pack 2
    • Windows XP Service Pack 2
  • You save this file to a disk that is formatted by using the NTFS file system.
  • You extract the files from the compressed file by using the Extract All Files wizard.
In this scenario, the modified date of the extracted files changes to the date that you extracted the files.

Note This problem does not occur when you use a third-party tool, such as WinZip, to extract the files.

CAUSE

This problem is a security feature of the Attachment Manager that is included in the operating system.

  2. Click the General tab, click Unblock, and then click OK.
  3. Extract the files from the compressed file.

Method 2: Copy the file to a different location

MORE INFORMATION

Internet Explorer has a Zone Identifier function. When you download a file from the Internet zone, this information is saved with the file. The Attachment Manager uses this function to handle the manipulation of downloaded files.
