Final answer:
To configure File History, connect the external drive, access File History through the Control Panel, and follow the instructions to turn on and configure preferences for the feature. There's no need for extra software, as File History is a feature of Windows, and the external drive should be NTFS-formatted, which is usually already done.
Step-by-step explanation:
To turn on and configure File History with a spare external drive connected to your computer or to a network location, you should follow these steps:Connect the external drive to your computer. Make sure the drive has sufficient free space and is properlyformatted, typically with NTFS.Go to the Control Panel and select 'System and Security'.Under the 'System and Security' options, click on 'Save backup copies of your files with File History'.Select 'Turn on File History' to enable it. You might need to choose the external drive you wish to use for File History if it's not selected automatically.Configure your preferences for how often File History backs up your files and how long versions are kept.
Note that there is no need to install separate File History software, as this is a built-in feature of the Windows Operating System. While the external drive does need to be formatted for use with File History, typically this is already done since external drives are often pre-formatted with the NTFS file system, which is compatible with File History.
