Safe to add files to a Windows 10 installion USB drive?

[wyldkytten]

I created a bootable Windows 10 installation USB drive on a 32GB flash drive. I was wondering it was safe to add a folder on there that would contain backups of my Favorites folder, any drivers I need for my hardware as well as other files? Or is it best just to leave it as a clean Windows install drive?

I have added things in a separate folder in the past (windows 8) and everything worked normally. I suspect the same here.
