Drag and drop file to leaf of tree control

Hello,

I want to drag a file from the desktop or windows explorer and drop it to the leaf of a tree in a tree control. Than the file is uploaded to some storgage and its name is shown under the leaf.

Is it possible to implement this with one of the tree controls?

If yes, can someone give me a hint, how to implemet it?

Is there any sap standard transaction, where this is implemented?

Do you know of any demo programm?

Thank you in advance,

Peter
