If you are not able to access files on your computer’s local storage while using a Virtual Lab application you may not have the correct permissions granted in Citrix Workspace. Use the following steps to allow read and write access to Citrix Workspace.
Launch a Virtual Lab application, but before you do any work, choose “preferences”, in the Citrix viewer menu.
In the File access section, select read and write. If you made a change you will need to close and reopen the app for the change to take effect.
