windows 10 download wires external drive it was downloaded to

[paugie]

As chapter 2 of my friend's computer woes...
Since I was away, I asked his daughter to DL Win10 so I could upgrade his Win7
She SMSs me.
How does she recover her files. Seems the download wiped her files from the external drive she downloaded it to.
I hope someone has encountered this and made a correction successfully.

What did she download?

As I recall, you have to go through extra steps to end up with an ISO, if that's what you were after.
