Not possible.
For futher clarification, could you state the use case for this requirement?
This will help to understand the need to provide an API call like this.
Thanks!
Yes, the use case would be informative.
You are really talking about using the Windows API, not the MediaBin API. If you are coding directly against the MB API, you could make your own call into Windows to get that information.
MediaBin API does not, and will not, expose that type of information directly and would represent a signifiant security hole.
