Client Drive Mapping (CDM) on Presentation Server 4.5, XenApp 5.0 is now called Citrix Drive Mapping Redirector (CDMR) .
Presentation Server 4.5 and XenApp 5.0, use the method of ‘network mapping’ the local drive of the user. This method only map local drives, not the network drivers of the user machine. So to map the network drivers we need to use script with ‘net use‘ command and to locate the drives from \CLIENT. Also the administrator has to use a log off script to delete the drives when the users log off.
In XenApp 6.0, the CDM uses the concept of redirection. In a session the mapped drives are classified as Network Drives and the redirected drivers are classified as Other. The users need to modify the policy to allow redirection for network drives on the client’s system. The applications can not find the redirected drives while searching. So the users would require searching \CLIENT inside the session and map the desired drive manually or with the scripts.
The Q disk is a network drive being redirected and the drives are recognized as ‘Others’, because the drives are not mapped but redirected.
