I've searched for information on "uupdbin" and found that it's related to a tool called "uupdump" or "uupdbin" which seems to be a part of the Windows utility "Universal USB Installer" or a tool for creating bootable USB drives.
The term stands for Unified Update Platform . This is a technology used by Microsoft (and by extension, devices that integrate with Windows ecosystems) to deliver updates more efficiently. sd card uupdbin
