Hello Ron,
Acknowledging all the details that you have provided.
Other people section will be created once a new user profile is logged into your PC. All their files, programs, and apps installed on their profile will be there as well. You can view Other People section by following this:
Press Windows + I > System > Storage > This PC (C:) > Scroll down to the bottom you'll see Other People.
If you can't view or manage files from there, you can access this from File Explorer. To do this:
Press Windows + E > This PC > Local Disk (C:) > Users > From here, all users who previously logged on to your device will show.
If you are the Administrator of the device you're using you'd be able to delete the user accounts and its file to lessen up the usage on your disk. To do this:
- Open Settings, and click/tap on the Accounts icon.
- Click/tap on Family & other people on the left side, click/tap on an account you want to delete on the right side, and click/tap on Remove.
- Click/tap onDelete account and data to confirm.
- When finished, you can close Settings if you like.
Once done, the user profile/s would be deleted along with its files. You can check again the Other People section and see if it's still eating large space on your drive.
