You Can View an NTFS Encrypted File in Thumbnail View (298608)



The information in this article applies to:

  • Microsoft Windows XP Professional

This article was previously published under Q298608

SYMPTOMS

If you encrypt a file by using the NTFS file system, and the view is set to Thumbnail, the contents of the file may still be visible. For example, if you encrypt an image file or an HTML file, and then you set it to the Thumbnail view, you will be able to see the image or HTML image on the thumbnail.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

Windows 2000 uses NTFS Native Streams to store thumbnail data whereas Windows XP uses a compressed database file (Thumbs.db) to increase performance. NTFS Native Streams provide Access Control List (ACL) security, but Thumbs.db does not.
