How to achieve parallel processing when a user uploads n files using windows explorer

How to achieve parallel processing when a user uploads n files? I've found that in the actual situation, the files are uploaded one by one in a serial manner, which leads to poor performance.

I can use multiple client instances, each uploads a file, thus achieving parallel upload of multiple files.
However, I need to develop a client by myself and then drag files into this client to initiate multiple SMB clients, right? I want to drag five files in Windows Explorer and have these five files uploaded concurrently.

Another question is whether the server can implement a new instruction - processing mode. When the same user uploads multiple files, can multiple connections and threads be enabled? Or is it possible to achieve this using asynchronous I/O?
