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.
