This option is only possible if all attendees have access to the shared folder location. This means they must be on the same network, whether this is a local network or a VPN. Unlike Azure this does not require a subscription, and the file size is only limited by the free space available on the drive. When using this option, we need to first select the shared folder where the dataset will be saved and then we can select the SIS or CZI file to be used for the session. When the template is saved the dataset is automatically uploaded and made available to all participants.
