How to limit the size of the RDP buffer and track who uses the buffer to transfer files?

Question

RDP

Hello.
There is information on the Internet, but the topic is not fully disclosed. I understand that it is impossible to limit the text / folder files by the type of information being transferred, is it possible to limit the buffer size, for example, to 2 MB? That is, copying the text should be left, it will be regulated by the size itself, as a result, no one will throw big data, if possible. Despite the availability of other means of data transfer, people in the organization still use the RDP buffer often, as a result, the terminal may hang.
How to track who exactly transmits data in this way, because the process, as I understand it, is carried out in the framework of explorer.exe (explorer), as far as I understand? How to identify which user is transferring files in this way and interrupt this process without affecting other users and without affecting other applications of this user?
