Initially, the server saves the file to a temporary directory. The application logic must then validate the file and move it to its permanent storage location. Storage Architectures: Where Do Uploaded Files Go?
For direct device-to-device uploads without intermediate servers, WebRTC data channels offer faster, private transfers. Ideal for large files between trusted users.
