In an on premise installation, the waterRIDE CLOUD server resides on a server on your LAN/WAN. Datasets accessed by the server can be stored locally (eg on an internal SSD drive for superior performance), and/or on your corporate network.
To access files that may be on your local machine or a USB drive, they will need to be copied to a location that the server can access (eg the servers local drive, or a common network drive).
Likewise, any waterRIDE projects that are created should be stored in similar locations.
