Hi Scott,
You don’t have to use putty (or a command line tool) to perform the steps Daniel describes. You can use the tool WinSCP and navigate, like explorer, to the locations as described in the post of Daniel and perform the copy and past actions (no command lines required, just copy and past). However within WINSCP you must login the QNAP NAS with SFTP (port 22) instate. As admin of course.
If you need help, please let me know and I’ll create a small guide.
