When launching your Desktop, it's possible that a dialog box pops up asking you to (dis)allow read/write access.
This is asked to set the level of access you want to grant to your local files.
We recommend to choose "read/write access", as it's required to access local files & USB devices.
You can also choose for "No access" or "Read-only access".
The setting can also be adjusted in the Citrix menu > Preferences > File Access.
