Reinstalling from back up disks

[Weetie]

I recenly had a problem with my system and was helped by a Microsoft Tech.
He backed-up my files on one disk and my emails on another. He then cleared
my system and reloaded Vista Home Basic. (As you can see from my lack of
technical terminology, I am have very little computer knowledge.) I have
tried to find out how to reload my backed up information but have been unable
to do so...and frankly am nervous that I may push the wrong button. Please
help me.

How did he back up these files, what types of files are they? What email
client?

He had connected to my system so I am not sure what he did. I just put the
disk in the drive when he told me to. The files are, templates, and word
files. My email address is a hot mail address.
