Hi, To copy files from Windows 7 to an external hard drive, plug in the drive, open Computer via the Start menu, and locate your files. Select the desired files/folders, right-click and choose Copy, then open the external drive in a new window, right-click in the empty space, and select Paste. See links to videos on the Internet
Also, the Windows 7 Backup and restore is still on Windows 10 (not sure about Window 11) Control Panel>Small Icons.
I would copy the files rather than moving them save mistakes.
