This is a feature request/question for Horizon View product - vIDM does not alter the behavior of RDS apps. Please post this in that forum.
Latest Horizon 6.2 supports these features. i.e. content stored on your desktop can be accessed by a RDS Published Application. You can also mapp local drives so they are accessible by RDS. So please have a look at our Horizon product.
Is that using the Horizon Client or HTML access? I read it could be done with the client but we are trying not to use the client for this project.
it would only be possible with the client
