How to make it easier to transfer files between windows

Modern desktop operating systems have a useful feature called drag'n'drop. That is, the ability to transfer files between windows and applications without copying.

This is not always convenient if you need to transfer several files. Or the second window is not yet open, and you have already moved the cursor over the victim. In this, and probably only in this case, the DropPoint application can be useful.

The utility has no settings or hot keys, which is bad. Because the DropPoint window is one-time and each time it needs to be reopened from the context menu in the tray.
