Hotkey modifier: The modifier for the function key to be sent when the relevant key combination [Alt] + [F<n>] is pressed

Configuring the Client Drive Mapping

Through drive mapping, each directory mounted on the device (including CD-ROMs and disk drives) is made available to your Citrix session.

You can specify which drives and paths are mapped during the logon. This applies to all Citrix sessions.

In the profile configurator, go to Apps > Citrix > Global Settings > Client Drive Mapping.
To add a client drive mapping, click .
Edit the settings according to your needs and click Confirm:

Enabled: Activate to make this drive available in Citrix sessions.
Drive to map: Choose a DOS-style drive letter under which the drive will appear on the Citrix Server.

If the drive letter you have selected is no longer available on the Citrix server, the specified directory or local drive will be given the next free letter during the logon.
Local drive path: Enter a Unix path name of the local directory to which the mapping is to refer. If you map a locally connected device, use the pre-defined path names available in the drop-down field.

Local (USB) devices which are to be used for drive mapping purposes must first be set up as storage devices.

Before you unplug a hotplug storage device from the device, you must safely remove it. Otherwise, data on the hotplug storage device can be damaged. Depending on the configuration, there is one or several possibilities to safely remove a hotplug storage device:

Click on
in the task bar. The taskbar is not available in a fullscreen session.
Click on in the in-session control bar. Depending on the configuration, the in-session control bar may be available in a fullscreen session.
Function Devices > Storage Devices > Disk Removal with further starting possibilities; amongst other things, a hotkey can be defined here.
If the following warning is displayed: Volume(s) still in use. Don't remove the device., then the hotplug storage device must not be removed. First, exit the program concerned or close all files or directories that reside on the hotplug storage device.
