Could not determine the target of the Drag&Drop operation. Either the shell extension is not installed properly, or you didn't drop the files into an explorer window.

|| A bug in Windows 10 version 1803 (April 2018 Update) breaks the extension. 1644 The latest version of WinSCP, when running this version of Windows, uses a different mechanism to determine a drop target. Future versions of WinSCP will allow using this method on any version of Windows.

Troubleshooting
Re-registering the shell extension (Windows only)
Especially on Vista or Windows 7 it can happen that Drag&Drop fails and you get an error message stating the shell extension doesn't work. In this case you may need to re-register it. Here's how:

1. Open a command prompt as administrator. This is important!

Start Menu - All Programs - Accessories: Right Click 'Command Prompt', select 'Run as administrator'

2. Navigate to the Filezilla program directory.

Example (32bit): cd "\Program Files\Filezilla FTP Client"
Example (64bit): cd "\Program Files (x86)\FileZilla FTP Client"

3. Re-register the shell extension.

Type 'regsvr32 fzshellext.dll' (without quotes of course)

4. If you have 64bit OS, you need to perform an additional step.

Type 'regsvr32 fzshellext_64.dll' (no quotes as well)

If you get the reply 'DllRegisterServer in ... succeeded.', you've done it (though you probably still need to reboot your computer).
