Clipborad and file transfer out of order

Hello,

I have two problems with the Remote Assitant.

The file transfer works well from the other computer onto my computer.
This link perfect one, everything understandable from it:

What are out of order:

From my computer onto the other computer how it is possible to send a file?

How it is possible to send a file through a clipboard onto the other computer?
The insert is not active on the other computer.

Thanks.
