Applicable Operating Systems:
Windows 2000 Professional
Windows XP Home / Pro / Media Center
Windows XP Professional x64 Edition
As a part of Easy Media Creator 8, the RoxWatch application stores metadata as part of a file that is located within an alternate data stream. When a file is indexed by RoxWatch so that it is accessible through Media Manager, there is an alternate data stream added. This information is similiar to a virtual sticky note. This virtual sticky note contains a unique identification number which is assigned to media files on your hard drive. Only media files which are indexed by RoxWatch will contain this information.
This feature assists users who move files to new locations on their hard drive by automatically updating their location. VideoWave and MyDVD projects for example contain pointers to images and videos that have been added to a project. If you move a file from one indexed location to another, typically when you attempt to open your saved project that image or video that was added will be missing in the project.
With this tagging however, once the new the file is indexed by RoxWatch your projects will automatically point to the new location of the files.
The unique identifier or tag is only unique to your computer, the same identification tag may exist on another customers computer for a different file. This information is only useful on your computer and as such does not exist and is not transferred anywhere else.
These data streams, sometimes called NTFS data streams, can only exist on NTFS hard disk partitions.
If you e-mail a file, the data stream is not included.
When you burn a file to CD/DVD, the data stream is not included.
If you attempt to copy a file which contains a data stream to a non-NTFS drive or USB storage device such as a USB memory key, you may receive you may receive the following error message:
Confirm Stream Loss
The file "filename.avi" has extra information attached to it that might be
lost if you continue copying. The contents of the file will not be
affected. Information that might be lost includes:
:Roxio: EMC Stream:$DATA
Do you want to proceed anyway?
To continue you should choose the "Yes" option and only the extra information that is tagged to this file will be removed as it is copied. This is working as designed, the tagging information can only be stored on NTFS partitions.
If you wish to stop this information from being created, you will need to right click on the RoxWatch or Media Manager Services icon in your system tray and choose "Stop Watching Folders". If you have hidden the system tray icon, you can access these options in the Media Manager application.
