I wish to make a copy of my BW10 USB thumb drive, essentially copying everything to another new USB thumb drive. In case I lose the original one, I will still have a backup copy.

Does anyone know if I can simply use the Copy & Paste functions of Windows (7 or 10) to achieve my goal?
Are there any hidden files that cannot be copied and might need a more powerful separate backup software?
If so, what do you suggest? Is freeware EaseUS Todo Backup Free good enough?

Thank you for your input.
