Shadow file
Navin Kaushik 6/21/2007 4:36:01 PM
I read the following documentation of WMP SDK 11 under conversion plug-in
section:

After Windows Media Player instantiates the conversion plug-in, the process
proceeds as follows:
1. The Player calls IWMPConvert::ConvertFile.
2. The plug-in converts the file provided in the bstrInputFile parameter
into an ASF format.
3. If the conversion fails for some reason, the plug-in returns an
appropriate failure code and the process stops.
4. If the conversion succeeds, the plug-in places the converted file into
the folder provided in the bstrDestinationFolder parameter and returns the
fully qualified path to the converted file through the pbstrOutputFile
parameter.
5. The plug-in returns a success code from ConvertFile.
6. The Player copies the converted file to a folder in the user's music
folder hierarchy. Exactly where the Player copies the file to depends on
content. As part of this process, the Player might rename the file.
7. The Player copies the original (unconverted) file to a folder in the
user's music folder hierarchy. As part of this process, the Player might
rename the file. This is the copy of the file that the Player uses when the
user syncs the content from the computer to a device that requires the
original file format. This file is called a shadow file.
8. The Player adds information about the converted file to the library. This
includes setting the value for the ShadowFilePath attribute to the new
location where the shadow file is saved.

Point 7 is not working as per mentioned above. WMP is not placing the
original file at the user's music folder.

Point 8: I could not understand the meaning of "The Player adds information
about the converted file to the library" , how can I verify it ?

Please give your valuable feedback.

Thanks,
Navin
